Get two integers from the user.
Then, display a message if the first integer is:
::::* less than,
::::* equal to, or
::::* greater than
the second integer.
Test the condition ''for each case separately'', so that ''all three comparison operators are used'' in the code.

Code is called as a subroutine (i.e. JSR Compare).
Specific OS/hardware routines for user input and printing are left unimplemented.
It should be noted that this is strictly an unsigned comparison.

The task of getting input from the user is much more difficult in assembly since it hasn't been done for you unlike nearly all other languages. So that part will be omitted to focus on the actual comparison.
In assembly, the only difference between a signed integer and an unsigned integer is the comparator(s) used to evaluate it. Therefore we have two different versions of this task.
===Unsigned Comparison===

Input/output is specific to hardware; this code assumes the integers are in registers a and b.
There is only one comparison instruction to use: 'not equal'.
<syntaxhighlight lang="asm">compare:
push psw
cjne a, b, clt
; a == b
; implement code here
jmp compare_
clt:
jc lt
; a > b
; implement code here
jmp compare_
lt:
; a < b
; implement code here
compare_:
pop psw
ret</syntaxhighlight>
Testing for (a <= b) or (a >= b) can be performed by changing the jumps.
=={{header|8th}}==
The user would put the numbers on the stack and then invoke 'compare':
<syntaxhighlight lang="forth">
: compare \ n m --
2dup n:= if "They are equal" . cr then
2dup n:< if "First less than second" . cr then
n:> if "First greater than second" . cr then ;

Alternatively one could use the "n:cmp" word

Note: Strictly speaking, it's preferable to use "==" when comparing integers as seen in this example. While the "=" sign will work as a comparison in most cases, technically it should be used for assignment, i.e. a = 3 when a is assigned the value of 3, as contrasted with a == 3, where the value of a is being compared with 3. FB will flag a warning when "==" is used to compare two single, doubles or floats since comparing real numbers can be inaccurate.

You can type this directly into a REPL:

(cond
Line 319 ⟶ 1,403:
((> a b) (format t "~A is greater than ~A." a b))
((= a b) (format t "~A is equal to ~A." a b))
(t (format t "Cannot determine relevance between ~A and ~B!" a b)))))</
After hitting enter, the REPL is expecting the two numbers right away.
You can enter the two numbers, and the result will print immediately.
Alternatively, you can wrap this code in a function definition:
<
(let ((a (read *standard-input*))
(b (read *standard-input*)))
Line 332 ⟶ 1,418:
((> a b) (format t "~A is greater than ~A." a b))
((= a b) (format t "~A is equal to ~A." a b))
(t (format t "Cannot determine relevance between ~A and ~B!" a b)))))</
Then, execute the function for better control:

The only conditional instruction we have is <tt>BRZ</tt> (branch on accumulator zero). We can therefore test for equality very quickly. To test for "greater than" or "less than", however, requires a loop.
If you run this program, it will halt awaiting user input. Toggle in the value of <math>x</math>, then click <tt>Enter</tt>, then toggle in <math>y</math>, then <tt>Enter</tt>, and then <tt>Run</tt>. <math>x</math> and <math>y</math> must both be unsigned eight-bit integers. The computer will halt with the accumulator storing 1 if <math>x</math>><math>y</math>, 0 if <math>x</math>=<math>y</math>, or -1 if <math>x</math><<math>y</math>; and it will be ready for a fresh pair of integers to be entered.

Fōrmulæ has an intrinsic expression for [[wp:Three-way_comparison|three-way comparison]] that works for integers and other types (decimal and rational numbers, strings, time expressions, etc). It returns expressions that flag one of the three possible results.

An alternative implementation could use a Python dictionary to house a small dispatch table to be indexed by the results of the built-in ''cmp()'' function. ''cmp()'' returns a value suitable for use as a comparison function in a sorting algorithm: -1, 0 or 1 for <, = or > respectively. Thus we could use:
{{works with|Python|2.x only, not 3.x}}
<
import sys
try:
a =
b =
except (ValueError, EnvironmentError), err:
print sys.stderr, "Erroneous input:", err
Line 1,636 ⟶ 3,482:
1: 'is greater than'
}
print a, dispatch[cmp(a,b)], b</
In this case the use of a dispatch table is silly. However, more generally in Python the use of dispatch dictionaries or tables is often preferable to long chains of '''''elif'''' clauses in a condition statement. Python's support of classes and functions (including [[currying]], partial function support, and lambda expressions) as first class objects obviates the need for a "case" or "switch" statement.

Comparisons in Snobol are not operators, but predicate functions that return a null string and generate a success or failure value which allows or blocks statement execution, and which can be tested for branching. Other numeric comparisons are ge (>=), le (<=) and ne (!= ). There is also a parallel set of L-prefixed predicates in modern Snobols for lexical string comparison.

=={{header|SSEM}}==
The SSEM only provides one conditional operation: <tt>011 Test</tt>, which causes execution to skip one instruction if the value in the accumulator is negative. We can use this to implement conditional tests along the lines of the following pseudocode:
<pre> accumulator := a - b;
if accumulator >= 0 then
(* a is not less than b, so *)
goto next_test
else
goto less;
next_test: accumulator := accumulator - 1;
if accumulator >= 0 then
goto greater
else
(* a and b are equal *)
accumulator := 0;
halt;
greater: accumulator := 1;
halt;
less: accumulator := -1;
halt</pre>
To run the SSEM program, load A into storage address 21 and B into storage address 22. No additional space is used. Like the pseudocode version, the program halts with the accumulator holding 1 if A>B, 0 if A=B, or -1 if A<B.

Other comparison operators are "<=", ">=" and "!=".
Line 1,964 ⟶ 4,308:
Note that Tcl doesn't really have a notion of a variable "type" - all variables are just strings of bytes and notions like "integer" only ever enter at interpretation time. Thus the above code will work correctly for "5" and "6", but "5" and "5.5" will also be compared correctly. It will not be an error to enter "hello" for one of the numbers ("hello" is greater than any integer). If this is a problem, the type can be expressly cast
<
or otherwise [[IsNumeric | type can be checked]] with "<tt>if { string is integer $x }...</tt>"
