Task
Loops/With multiple ranges
You are encouraged to solve this task according to the task description, using any language you may know.

Some languages allow multiple loop ranges, such as the PL/I example (snippet) below.

                                       /* all variables are DECLARED as integers. */
          prod=  1;                    /*start with a product of unity.           */
           sum=  0;                    /*  "     "  "   sum    " zero.            */
             x= +5;
             y= -5;
             z= -2;
           one=  1;
         three=  3;
         seven=  7;
                                       /*(below)  **  is exponentiation:  4**3=64 */
           do j=   -three  to     3**3        by three   ,
                   -seven  to   +seven        by   x     ,
                      555  to      550 - y               ,
                       22  to      -28        by -three  ,
                     1927  to     1939                   ,
                        x  to        y        by   z     ,
                    11**x  to    11**x + one;
                                                        /* ABS(n) = absolute value*/
           sum= sum + abs(j);                           /*add absolute value of J.*/
           if abs(prod)<2**27 & j¬=0  then prod=prod*j; /*PROD is small enough & J*/
           end;                                         /*not 0, then multiply it.*/
                     /*SUM and PROD are used for verification of J incrementation.*/
         display (' sum= ' ||  sum);                    /*display strings to term.*/
         display ('prod= ' || prod);                    /*   "       "     "   "  */


Task

Simulate/translate the above PL/I program snippet as best as possible in your language,   with particular emphasis on the   do   loop construct.

The   do   index must be incremented/decremented in the same order shown.

If feasible, add commas to the two output numbers (being displayed).

Show all output here.

      A simple PL/I   DO  loop  (incrementing or decrementing)  has the construct of:

            DO variable = start_expression    {TO ending_expression]       {BY increment_expression} ;
                 ---or---
            DO variable = start_expression    {BY increment_expression}    {TO ending_expression]    ;  

      where it is understood that all expressions will have a value.  The  variable  is normally a 
      scaler variable,  but need not be  (but for this task, all variables and expressions are declared
      to be scaler integers).   If the   BY   expression is omitted,  a   BY   value of unity is used.
      All expressions are evaluated before the   DO   loop is executed,  and those values are used
      throughout the   DO   loop execution   (even though, for instance,  the value of   Z   may be
      changed within the   DO   loop.    This isn't the case here for this task.  

      A multiple-range   DO   loop can be constructed by using a comma (,) to separate additional ranges
      (the use of multiple   TO   and/or   BY   keywords).     This is the construct used in this task.
 
      There are other forms of   DO   loops in PL/I involving the  WHILE  clause,  but those won't be 
      needed here.    DO  loops without a   TO   clause might need a   WHILE   clause  or some other 
      means of exiting the loop  (such as  LEAVE,  RETURN,  SIGNAL,  GOTO,  or  STOP),  or some other 
      (possible error) condition that causes transfer of control outside the  DO  loop.
 
      Also, in PL/I, the check if the   DO   loop index value is outside the range is made at the 
      "head"  (start)  of the   DO  loop,  so it's possible that the   DO   loop isn't executed,  but 
      that isn't the case for any of the ranges used in this task. 

      In the example above, the clause:                    x    to y       by z     
      will cause the variable   J   to have to following values  (in this order):  5  3  1  -1  -3  -5

      In the example above, the clause:                 -seven  to +seven  by x  
      will cause the variable   J   to have to following values  (in this order):  -7  -2   3

ALGOL W

AutoHotkey

As with most of the other languages, AutoHotkey doesn't support multiple loop ranges, so a workaround function is used instead.

for_J(doFunction, start, stop, step:=1){
	j := start
	while (j<=stop) && (start<=stop) && (step>0)
		%doFunction%(j),		j+=step
	while (j>=stop) && (start>stop) && (step<0)
		%doFunction%(j),		j+=step
}
Examples:
prod := 1
sum := 0
x := +5
y := -5
z := -2
one :=  1
three :=  3
seven :=  7

for_J("doTHis", -three, 3**3, three)

        one   = 1,
        three = 3,
        seven = 7;

    auto summingValues = vector<int>{};

    for(int n = -three; n <= pow(3, 3); n += three)
        summingValues.push_back(n);
    for(int n = -seven; n <= seven; n += x)
        summingValues.push_back(n);
    for(int n = 555; n <= 550 - y; ++n)
        summingValues.push_back(n);
    for(int n = 22; n >= -28; n -= three)
        summingValues.push_back(n);
    for(int n = 1927; n <= 1939; ++n)
        summingValues.push_back(n);
    for(int n = x; n >= y; n += z)
        summingValues.push_back(n);

Delphi

end;

procedure process(j: Int64);

Eiffel

Eiffel does not support multiple ranges in the same fashion as PL/I. However, it does have an across loop, which does the trick, together with an inline agent (lambda function).

class
	APPLICATION

create
	make

feature

	prod, sum, x, y, z, one, three, seven: INTEGER

	make
		local
			process: PROCEDURE
		do
			prod := 1; x := 5; y := -5; z := -2; one := 1; three := 3; seven := 7
			process := (agent (j: INTEGER)
								do
									print (j.out + ", ")
									sum := sum + j.abs
									if prod.abs < 2^27 and j /= 0 then
										prod := prod * j
									end
								end)

			across (-three |..| (3^3).truncated_to_integer).new_cursor + (three - 1)  as ic loop process.call (ic.item) end
			across (-seven |..| seven).new_cursor + (x - 1)	as ic loop process.call (ic.item) end
			across 555 |..| (550 - y) as ic loop process.call (ic.item) end
			across (-26 |..| 22).new_cursor + (three - 1) as ic loop process.call (ic.item) end
			across 1927 |..| 1939 as ic loop process.call (ic.item) end
			across (y |..| x).new_cursor + (-z - 1)	as ic loop process.call (ic.item) end
			across (11^x).truncated_to_integer |..| ((11^x).truncated_to_integer + 1) as ic loop process.call (ic.item) end

			print ("%N")
			print ("sum = " + sum.out + "%N") 		-- sum = 348,173
			print ("prod = " + prod.out + "%N")		-- prod = -793,618,560
		end

end

Alternatively, there is the "symbolic form" of the across loop, which modifies the code as follows:

class
	APPLICATION

create
	make

feature

	prod, sum, x, y, z, one, three, seven: INTEGER

	make

			process := (agent (j: INTEGER)
								do
									print (j.out + ", ")
									sum := sum + j.abs
									if prod.abs < 2^27 and j /= 0 then
										prod := prod * j
									end
								end)

			 ic: (-three |..| (3^3).truncated_to_integer).new_cursor + (three - 1) ¦ process.call (ic) 
			 ic: (-seven |..| seven).new_cursor + (x - 1) ¦ process.call (ic) 
			 ic:555 |..| (550 - y) ¦ process.call (ic)

			 ic: (y |..| x).new_cursor + (-z - 1) ¦ process.call (ic) 
			 ic: (11^x).truncated_to_integer |..| ((11^x).truncated_to_integer + 1) ¦ process.call (ic) 

			print ("%N")
			print ("sum = " + sum.out + "%N") 		-- sum = 348,173
			print ("prod = " + prod.out + "%N")		-- prod = -793,618,560

Go

Nothing fancy from Go here (is there ever?), just a series of individual for loops.

package main

import "fmt"

func pow(n int, e uint) int {
    if e == 0 {
        return 1
    }
    prod := n
    for i := uint(2); i <= e; i++ {
        prod *= n
    }
    return prod
}

func abs(n int) int {
    if n >= 0 {
        return n
    }
    return -n
}

func commatize(n int) string {
    s := fmt.Sprintf("%d", n)
    if n < 0 {
        s = s[1:]
    }
    le := len(s)
    for i := le - 3; i >= 1; i -= 3 {
        s = s[0:i] + "," + s[i:]
    }
    if n >= 0 {
        return " " + s
    }
    return "-" + s
}

func main() {
    prod := 1
    sum := 0
    const (
        x     = 5
        y     = -5
        z     = -2
        one   = 1
        three = 3
        seven = 7
    )
    p := pow(11, x)
    var j int

    process := func() {
        sum += abs(j)
        if abs(prod) < (1<<27) && j != 0 {
            prod *= j
        }
    }

    for j = -three; j <= pow(3, 3); j += three {
        process()
    }
    for j = -seven; j <= seven; j += x {
        process()

        process()
    }
    fmt.Println("sum  = ", commatize(sum))
    fmt.Println("prod = ", commatize(prod))

Groovy

Solution:

def (prod, sum, x, y, z, one, three, seven) = [1, 0, +5, -5, -2, 1, 3, 7]

for (
    j in (
        ((-three) .. (3**3)       ).step(three)
      + ((-seven) .. (+seven)     ).step(x)
      + (555      .. (550-y)      )
      + (22       .. (-28)        ).step(three)    // This is correct!
      // Groovy interprets positive step size as stride through the LIST ELEMENTS as ordered
      // and negative step size as stride through the REVERSED LIST ELEMENTS as ordered
      //   so step(-3) gives:   -28, -25, -22, ... ,  20
      //   while step(3) gives:  22,  19,  16, ... , -26
      + (1927     .. 1939         )
      + (x        .. y            ).step(z)
      + (11**x    .. (11**x + one))
    )
) {

    sum = sum + j.abs()
    if ( prod.abs() < 2**27 && j != 0) prod *= j
}

println " sum= ${sum}"
println "prod= ${prod}"

Output:

 sum= 348177
prod= -793618560

Haskell

Haskell does not have loops. Programmers use either explicit recursion or recursive schemes (folds or unfolds) for looping. The following code mimics the PL/1 example using composition of left folds in order to handle multiple ranges:

loop :: (b -> a -> b) -> b -> [[a]] -> b
loop = foldl . foldl

example = let
  x = 5
  y = -5
  z = -2
  one = 1
  three = 3
  seven = 7
  in
    loop
    -- body
    (
      \(sum, prod) j ->
        (
          sum + abs j,
          if abs prod < 2^27 && j /= 0
          then prod * j else prod
        )
    )
    -- initial state
    (0, 1)
    -- ranges
    [ [-three, -three + three .. 3^3]
      , [-seven, -seven + x .. seven]
      , [555 .. 550 - y]
      , [22, 22 - three .. -28]
      , [1927 .. 1939]
      , [x, x + z .. y]
      , [11^x ..  11^x + one] ]

Java

Java does not support multiple ranges. Use list to simulate multiple ranges. Accumulate values in a list, then iterate over the list.

With Java 8, streams are available. Streams can be concatenated. However, the Java 9 feature takeWhile is important to this task to specify the iteration limit.

Maintain formatting similar to the original code.

jq

Works with: jq

Works with gojq, the Go implementation of jq

jq is stream-oriented, and so the "multiple ranges" feature comes for free, that is, it just involves stream concatenation with the "," operator.

The only wrinkle is that jq's `range` filters exclude the "right-hand" limit; to facilitate comparison with the PL/I code, the adjustment (e.g. "1 + ...") has been made explicit.

Since the only variables that are updated within the body of the loop are "sum" and "prod", the others could be defined as constants (i.e. as $-variables), but again to facilitate comparison with the PL/I code, this has not been done.

# If using gojq, one may want to preserve integer precision, so:
def power($b): . as $in | reduce range(0;$b) as $i (1; . * $in);

{ prod: 1,                             #  start with a product of unity.
  sum:  0,                             #  henceforth skip redundant comments.
    x:  5,
    y: -5,
    z: -2,
  one:  1,
  three: 3,
  seven: 7 }
| .x as $x  
| reduce (range(-.three; 1 + 3|power(3); .three),
          range(-.seven; 1 + .seven;     .x),
          range(    555; 1 +  550 - .y),
          range(     22; -1 -28;          -.three),
          range(1927   ; 1 + 1939),
          range(.x     ; .y;              .z),
          range(11|power($x); 1 + ( 11 | power($x)) + .one)) as $j (.;
             .sum += ($j|length)                         # add absolute value of $j (!)
             | if (.prod|length) < (2|power(27)) and $j != 0
	       then .prod *= $j
	       else .

Kotlin

Using a series of individual for loops:

// Version 1.2.70

import kotlin.math.abs

infix fun Int.pow(e: Int): Int {
    if (e == 0) return 1
    var prod = this
    for (i in 2..e) {
        prod *= this
    }
    return prod
}

fun main(args: Array<String>) {
    var prod = 1
    var sum = 0
    val x = 5
    val y = -5
    val z = -2
    val one = 1
    val three = 3
    val seven = 7
    val p = 11 pow x
    fun process(j: Int) {
        sum += abs(j)
        if (abs(prod) < (1 shl 27) && j != 0) prod *= j
    }

    for (j in -three..(3 pow 3) step three) process(j)
    for (j in -seven..seven step x) process(j)
    for (j in 555..550-y) process(j)
    for (j in 22 downTo -28 step three) process(j)
    for (j in 1927..1939) process(j)
    for (j in x downTo y step -z) process(j)
    for (j in p..p + one) process(j)
    System.out.printf("sum  = % ,d\n", sum)
    System.out.printf("prod = % ,d\n", prod)
}
Output:
sum  =  348,173
prod = -793,618,560

The following version does it in a similar way to PL/I and Algol-60, i.e. without defining a function to process the loop, using a single loop, and without creating a list from which to iterate:

import kotlin.math.abs
import kotlin.math.pow

private infix fun Int.`^`(exponent: Int): Int = toDouble().pow(exponent).toInt()

fun main() {
    var prod = 1
    var sum = 0
    val x = 5
    val y = -5
    val z = -2
    val one = 1
    val three = 3
    val seven = 7
    val p = 11 `^` x

    for (j in sequenceOf(
        -three..(3 `^` 3) step three,
        -seven..seven step x,
        555..550-y,
        22 downTo -28 step three,
        1927..1939,
        x downTo y step -z,
        p..p + one
    ).flatten()) {
        sum += abs(j)
        if (abs(prod) < (2 `^` 27) && j != 0) prod *= j
    }
    System.out.printf("sum  = % ,d\n", sum)
    System.out.printf("prod = % ,d\n", prod)
}
Output:
sum  =  348,173
prod = -793,618,560

Lua

Not directly supported, i.e. no true multi-range loops, but.. all that's really needed is a helper function to populate the list of values, aiming to specify the ranges with a syntax as-close-as-manageable to mimic that given in task description (iteration is then trivial):

-- support:
function T(t) return setmetatable(t, {__index=table}) end
table.range = function(t,a,b,c) local s=T{} for i=a,b,c or 1 do s[#s+1]=i end return s end
table.clone = function(t) local s=T{} for k,v in ipairs(t) do s[k]=v end return s end
table.chain = function(t,u) local s=t:clone() for i=1,#u do s[#s+1]=u[i] end return s end
unpack = unpack or table.unpack -- polyfill 5.2 vs 5.3

-- impl:
-- Multi-Range-Loop
-- param: table of tables of range specs
-- return: iterator over the chain of all ranges
function mrl(tt)
  local s=T{}
  for _,t in ipairs(tt) do s=s:chain(T{}:range(unpack(t))) end
  return ipairs(s)
end

-- demo:
prod,sum,x,y,z,one,three,seven = 1,0,5,-5,-2,1,3,7
for _,j in mrl{
  { -three,    3^3,  three },
  { -seven,  seven,      x },
  {    555,  550-y         },

M2000 Interpreter

Using lambda functions and a final While End While to perform a multiple range.

Values by default are double, but we can make them Long (32 bit integer), or Decimal or Currency or single (prod for single has less accuracy here), but not integer (16 bit) because we get overflow.

In M2000 expressions can change numeric type to hold the produced value. Variables take once the type, so we get overflow if we pass a value frome an expression which can't convert to variable's type.

Module MultipleLoop {
	def long prod=1, sum=0, x=+5,y=-5, z=-2, one=1, three=3, seven=7, j
	Range=lambda (a, b, c=1) ->{
		=lambda a, b, c (&f)-> {
			if compare(a,b)=sgn(c) then =false else =true: f=a: a+=c

	}
	MultipleRange=Lambda -> {

			k++ : always

Nim

Nim doesn’t provide loops with multiple ranges. There are several ways to translate the PL/1 program: using a sequence of for loops, using a sequence of while loops, using an iterator and, probably, too, some way using macros.

Using a sequence of loops

This solution is the obvious one, but it supposes that the direction of the loop is known (i.e. the sign of the step is known) as we have to choose between iterators “countup” and “countdown”. Using this method, the PL/1 example can be translated the following way:

import math, strutils

var
  prod = 1
  sum = 0

let
  x = +5
  y = -5

let s = ($sum).insertSep(',')
let p = ($prod).insertSep(',')
let m = max(s.len, p.len)
echo " sum = ", s.align(m)
echo "prod = ", p.align(m)

Note that for “countdown” we must change the sign of the step to insure that it is positive.

Output:
 sum =      348,173
prod = -793,618,560

Using an iterator

If the sign of the step is not known (or may vary), it is no longer possible to use the previous method. One could use a while loop but it seems better to use an iterator.

import math, strutils

var
  prod = 1
  sum = 0

let
  x = +5
  y = -5
  z = -2
  one = 1
  three = 3
  seven = 7

type Range = tuple[first, last, step: int]

func initRange(first, last, step = 1): Range = (first, last, step)

iterator loop(ranges: varargs[Range]): int =
  for r in ranges:
    if r.step > 0:
      for i in countup(r.first, r.last, r.step):
        yield i
    elif r.step < 0:
      for i in countdown(r.first, r.last, -r.step):
        yield i
    else:
      raise newException(ValueError, "step cannot be zero")

for j in loop(initRange(-three, 3^3, three),
              initRange(-seven, seven, x),
              initRange(555, 550 - y),
              initRange(22, -28, three),
              initRange(1927, 1939),
              initRange(x, y, -z),
              initRange(11^x, 11^x + one)):
  sum += abs(j)
  if abs(prod) < 2^27 and j != 0: prod *= j

let s = ($sum).insertSep(',')
let p = ($prod).insertSep(',')
let m = max(s.len, p.len)
echo " sum = ", s.align(m)
echo "prod = ", p.align(m)

Note that we have defined a function “initRange” to create the ranges. This is needed to make the step optional. If we suppressed this requirement (i.e. we required the step to be always specified), we could get ride of “initRange” and write the loop this way:

for j in loop((-three, 3^3, three),
              (-seven, seven, x),
              (555, 550 - y),
              (22, -28, three),
              (1927, 1939, 1),
              (x, y, -z),
              (11^x, 11^x + one)):
  sum += abs(j)
  if abs(prod) < 2^27 and j != 0: prod *= j

Picat

Picat has support for multiple loop variables, but the index variables for each range must be different:

foreach(I in 1..3, J in 4..6, K in 7..9)
  % ...
end

Here's a variant using the single loop variable J.

go =>
   Prod=  1,
    Sum=  0,
      X= +5,
      Y= -5,
      Z= -2,
    One=  1,
  Three=  3,
  Seven=  7,
  Ranges = [-Three..Three..3**3,
            -Seven..X.. +Seven,
            555..550-Y,
            22..-Three..-28,
            1927..1939,
            X..Z..Y,
            11**X..11**X + One
           ], 
  foreach(Range in Ranges, J in Range)
    Sum := Sum + abs(J),
    if abs(Prod) < 2**27, J != 0 then
      Prod := Prod * J
    end
  end,                                        
  println(sum=Sum),
  println(prod=Prod),
  nl.
Output:
sum = 348173
prod = -793618560

Another approach is to first concatenate the ranges and then flatten to a single list:

  % ...
  foreach(J in [-Three..Three..3**3,
                -Seven..X.. +Seven,
                555..550-Y,
                22..-Three..-28,
                1927..1939,
                X..Z..Y,
                11**X..11**X + One
                ].flatten
    )
    Sum := Sum + abs(J),
    if abs(Prod) < 2**27, J != 0 then
      Prod := Prod * J
    end
  end,

Loop

Raku

(formerly Perl 6)

This task is really conflating two separate things, (at least in Raku). Sequences and loops are two different concepts and may be considered / implemented separately from each other.

Yes, you can generate a sequence with a loop, and a loop can use a sequence for an iteration value, but the two are somewhat orthogonal and don't necessarily overlap.

Sequences are first class objects in Raku. You can (and typically do) generate a sequence using the (appropriately enough) sequence operator and can assign it to a variable and/or pass it as a parameter; the entire sequence, not just it's individual values. It may be used in a looping construct, but it is not necessary to do so.

Various looping constructs often do use sequences as their iterator but not exclusively, possibly not even in the majority.


Displaying the j sequence as well since it isn't very large.

REXX

Programming note:   the (sympathetic) trailing semicolons (;) after each REXX statement are optional,   they are only there to mimic what the PL/I language requires after each statement.

The technique used by this REXX version is to "break up" the various   do   iterating clauses (ranges) into separate   do   loops,   and have them invoke a subroutine to perform the actual computations.

/*REXX program emulates a multiple─range  DO  loop  (all variables can be any numbers). */

Ruby

Uses chaining of enumerables, which was introduced with Ruby 2.6

x, y, z, one, three, seven = 5, -5, -2, 1, 3, 7


enums = (-three).step(3**3, three) +
        (-seven).step(seven, x) +
        555     .step(550-y, -1) +
        22      .step(-28, -three) +
        (1927..1939) +                # just toying, 1927.step(1939) is fine too
        x       .step(y, z) +
        (11**x) .step(11**x + one)
# enums is an enumerator, consisting of a bunch of chained enumerators,
# none of which has actually produced a value.

puts "Sum of absolute numbers:  #{enums.sum(&:abs)}"
prod = enums.inject(1){|prod, j| ((prod.abs < 2**27) && j!=0) ? prod*j : prod}
puts "Product (but not really): #{prod}"
Output:
Sum of absolute numbers:  348173
Product (but not really): -793618560

Smalltalk

Ranges (called Interval in Smalltalk) are collections, which - like all collections - can be concatenated with the , (comma) message. Intervals are created by sending a to: or to:by: message to a magnitude-like thingy (i.e. other than numbers are possible):

prod := 1.        
sum := 0.
x := 5.
y := -5.
z := -2.
one := 1.
three := 3.
seven := 7.

(three negated to: 3**3  by: three       ) ,
(seven negated to: seven by: x           ) ,
(555           to: 550-y                 ) ,
(22            to: -28  by: three negated) ,
(1927          to: 1939                  ) ,
(x             to: y    by:z             ) ,
(11**x         to: 11**x + one           )
    do:[:j |
        sum := sum + j abs.
        ((prod abs < (2**27)) and:[ j ~= 0 ]) ifTrue:[
            prod := prod*j
        ].
    ].
Transcript show:' sum = '; showCR:sum.
Transcript show:'prod = '; showCR:prod

The above creates a temporary "collection of ranges" and enumerates that, which might be inconvenient, if the collections are huge.
One alternative is to loop over each individually.

Of course, we definitely don't want to retype the loop body and we usually don't want to the code to be non-local (i.e. define another method for it).
That's what blocks (aka lambdas or anonymous functions) are perfect for:

prod := 1.        
sum := 0.
x := 5.
y := -5.
z := -2.
one := 1.
three := 3.
seven := 7.

action := 
    [:j |
       sum := sum + j abs.
        ((prod abs < (2**27)) and:[ j ~= 0 ]) ifTrue:[
            prod := prod*j
        ].
    ].

(three negated to: 3**3  by: three       ) do:action.
(seven negated to: seven by: x           ) do:action.
(555           to: 550-y                 ) do:action.
(22            to: -28  by: three negated) do:action.
(1927          to: 1939                  ) do:action.
(x             to: y    by:z             ) do:action.
(11**x         to: 11**x + one           ) do:action.
Transcript show:' sum = '; showCR:sum.
Transcript show:'prod = '; showCR:prod

As another alternative to the first solution above, we can loop over the ranges. This avoids the concatenations and generation of the intermediate big collection (which does not really make a difference here, but would, if each collection consisted of millions of objects):

Works with: Smalltalk/X
...
{
    (three negated to: 3**3  by: three       ) .
    (seven negated to: seven by: x           ) .
    (555           to: 550-y                 ) .
    (22            to: -28  by: three negated) .
    (1927          to: 1939                  ) .
    (x             to: y    by:z             ) .
    (11**x         to: 11**x + one           ) .
} do:[:eachRange |
    eachRange 
        select:[:j | ((prod abs < (2**27)) and:[ j ~= 0 ]) ]
        thenDo:[:j | prod := prod*j ].
    ]
].
...

Notice: this creates only 8 objects and also demonstrates an alternative element selection scheme, which may be more readable.

Output:
  sum = 348173
 prod = -793618560

Note) Dialects with no **-method should use raisedTo:, or else define an alias for it in Number as:

** arg
    ^ self raisedTo: arg

Visual Basic .NET

VB.NET loops can't have multiple ranges, so this implementation will use the For Each loop and demonstrate various functions that produce concatenated ranges.

Composite formatting is used to add digit separators.

Using the following to provide the functionality of the For loop as a function,

Partial Module Program
    ' Stop and Step are language keywords and must be escaped with brackets.
    Iterator Function Range(start As Integer, [stop] As Integer, Optional [step] As Integer = 1) As IEnumerable(Of Integer)
        For i = start To [stop] Step [step]
            Yield i
        Next
    End Function
End Module

and Enumerable.Concat (along with extension method syntax) to splice the ranges, the program ends up looking like this:

Imports System.Globalization

Partial Module Program
    Sub Main()
        ' All variables are inferred to be of type Integer.
        Dim prod = 1,
            sum = 0,
            x = +5,
            y = -5,
            z = -2,
            one = 1,
            three = 3,
            seven = 7

        ' The exponent operator compiles to a call to Math.Pow, which returns Double, and so must be converted back to Integer.
        For Each j In Range(-three,       CInt(3 ^ 3),        3     ).
               Concat(Range(-seven,       +seven,             x     )).
               Concat(Range(555,          550 - y                   )).
               Concat(Range(22,           -28,                -three)).
               Concat(Range(1927,         1939                      )).
               Concat(Range(x,            y,                  z     )).
               Concat(Range(CInt(11 ^ x), CInt(11 ^ x) + one        ))

            sum = sum + Math.Abs(j)
            If Math.Abs(prod) < 2 ^ 27 AndAlso j <> 0 Then prod = prod * j
        Next

        ' The invariant format info by default has two decimal places.
        Dim format As New NumberFormatInfo() With {
            .NumberDecimalDigits = 0
        }

        Console.WriteLine(String.Format(format, " sum= {0:N}", sum))
        Console.WriteLine(String.Format(format, "prod= {0:N}", prod))
    End Sub
End Module

To improve the program's appearance, a ConcatRange method can be defined to combine the two method calls,

    <Runtime.CompilerServices.Extension>
    Function ConcatRange(source As IEnumerable(Of Integer), start As Integer, [stop] As Integer, Optional [step] As Integer = 1) As IEnumerable(Of Integer)
        Return source.Concat(Range(start, [stop], [step]))
    End Function

which results in a loop that looks like this:

        For Each j In Range(-three,       CInt(3 ^ 3),        3     ).
                ConcatRange(-seven,       +seven,             x     ).
                ConcatRange(555,          550 - y                   ).
                ConcatRange(22,           -28,                -three).
                ConcatRange(1927,         1939                      ).
                ConcatRange(x, y,         z                         ).
                ConcatRange(CInt(11 ^ x), CInt(11 ^ x) + one        )
        Next

An alternative to avoid the repeated method calls would be to make a Range function that accepts multiple ranges, in this case as a parameter array of tuples.

    Function Range(ParamArray ranges() As (start As Integer, [stop] As Integer, [step] As Integer)) As IEnumerable(Of Integer)
        ' Note: SelectMany is equivalent to bind, flatMap, etc.
        Return ranges.SelectMany(Function(r) Range(r.start, r.stop, r.step))
    End Function

Note, however, that the inability to have a heterogenous array means that specifying the step is now mandatory. Using a parameter array of arrays is slightly less clear but results in the tersest loop.

    Function Range(ParamArray ranges As Integer()()) As IEnumerable(Of Integer)
        Return ranges.SelectMany(Function(r) Range(r(0), r(1), If(r.Length < 3, 1, r(2))))
