You are encouraged to solve this task according to the task description, using any language you may know.
- Task
Provide an algorithm as per the Calendar task, except the entire code for the algorithm must be presented entirely without lowercase.
Also - as per many 1969 era line printers - format the calendar to nicely fill a page that is 132 characters wide.
(Hint: manually convert the code from the Calendar task to all UPPERCASE)
This task also is inspired by Real Programmers Don't Use PASCAL by Ed Post, Datamation, volume 29 number 7, July 1983.
THE REAL PROGRAMMER'S NATURAL HABITAT "Taped to the wall is a line-printer Snoopy calender for the year 1969."
Moreover this task is further inspired by the long lost corollary article titled:
"Real programmers think in UPPERCASE"!
Note: Whereas today we only need to worry about ASCII, UTF-8, UTF-16, UTF-32, UTF-7 and UTF-EBCDIC encodings, in the 1960s having code in UPPERCASE was often mandatory as characters were often stuffed into 36-bit words as 6 lots of 6-bit characters. More extreme words sizes include 60-bit words of the CDC 6000 series computers. The Soviets even had a national character set that was inclusive of all 4-bit, 5-bit, 6-bit & 7-bit depending on how the file was opened... And one rogue Soviet university went further and built a 1.5-bit based computer.
Of course... as us Boomers have turned into Geezers we have become HARD OF HEARING, and suffer from chronic Presbyopia, hence programming in UPPERCASE is less to do with computer architecture and more to do with practically. :-)
For economy of size, do not actually include Snoopy generation in either the code or the output, instead just output a place-holder.
FYI: a nice ASCII art file of Snoopy can be found at textfiles.com. Save with a .txt extension.
Trivia: The terms uppercase and lowercase date back to the early days of the mechanical printing press. Individual metal alloy casts of each needed letter, or punctuation symbol, were meticulously added to a press block, by hand, before rolling out copies of a page. These metal casts were stored and organized in wooden cases. The more often needed miniscule letters were placed closer to hand, in the lower cases of the work bench. The less often needed, capitalized, majiscule letters, ended up in the harder to reach upper cases.
360 Assembly
This is for real programmers who code only in assembler :). The code could have been run in april 1964, punched on 80-column cards, read on a card reader, and printed with a 132-column line printer on fan-folded paper with perforated edges. <lang 360asm>* CALENDAR FOR REAL PROGRAMMERS 05/03/2017 CALENDAR CSECT

Ada
In Ada, the task is really easy, because Ada is case insensitive. I.e., one could simply replicate the code from Ada solution of the calendar task and convert every lowercase character to uppercase. Instead of doing that, the implementation below reuses the package "PRINTABLE_CALENDAR" (same as "Printable_Calendar" or "printable_calendar") from the calendar task:
<lang Ada>WITH PRINTABLE_CALENDAR;
PROCEDURE REAL_CAL IS
C: PRINTABLE_CALENDAR.CALENDAR := PRINTABLE_CALENDAR.INIT_132
((WEEKDAY_REP =>
"MO TU WE TH FR SA SO",
MONTH_REP =>
(" JANUARY ", " FEBRUARY ",
" MARCH ", " APRIL ",
" MAY ", " JUNE ",
" JULY ", " AUGUST ",
" SEPTEMBER ", " OCTOBER ",
" NOVEMBER ", " DECEMBER ")
));
BEGIN
C.PRINT_LINE_CENTERED("[SNOOPY]");
C.NEW_LINE;
C.PRINT(1969, "NINETEEN-SIXTY-NINE");
END REAL_CAL;</lang>

D keywords are lower case, so this silly solution uses the whole Calendar Task code, with small changes and all in upper case, in a text file named "CALENDAR":
IMPORT STD.STDIO, STD.DATETIME, STD.STRING, STD.CONV,
STD.ALGORITHM, STD.ARRAY;
VOID PRINT_CALENDAR(IN UINT YEAR, IN UINT COLS)
IN {
ASSERT(COLS > 0 && COLS <= 12);
} BODY {
STATIC ENUM CAMEL_CASE = (STRING[] PARTS) PURE =>
PARTS[0] ~ PARTS[1 .. $].MAP!CAPITALIZE.JOIN;
IMMUTABLE ROWS = 12 / COLS + (12 % COLS != 0);
MIXIN("AUTO DATE = " ~ "DATE(YEAR, 1, 1);".CAPITALIZE);
ENUM STRING S1 = CAMEL_CASE("DAY OF WEEK".SPLIT);
MIXIN(FORMAT("AUTO OFFS = CAST(INT)DATE.%S;", S1));
CONST MONTHS = "JANUARY FEBRUARY MARCH APRIL MAY JUNE
JULY AUGUST SEPTEMBER OCTOBER NOVEMBER DECEMBER"
.SPLIT.MAP!CAPITALIZE.ARRAY;
STRING[8][12] MONS;
FOREACH (IMMUTABLE M; 0 .. 12) {
MONS[M][0] = MONTHS[M].CENTER(21);
MONS[M][1] = " " ~ "SU MO TU WE TH FR SA"
.SPLIT.MAP!CAPITALIZE.JOIN(" ");
ENUM STRING S2 = CAMEL_CASE("DAYS IN MONTH".SPLIT);
MIXIN(FORMAT("IMMUTABLE DIM = DATE.%S;", S2));
FOREACH (IMMUTABLE D; 1 .. 43) {
IMMUTABLE DAY = D > OFFS && D <= OFFS + DIM;
IMMUTABLE STR = DAY ? FORMAT(" %2S", D-OFFS) : " ";
MONS[M][2 + (D - 1) / 7] ~= STR;
}
OFFS = (OFFS + DIM) % 7;
DATE.ADD!"MONTHS"(1);
}
FORMAT("[%S %S]", "SNOOPY".CAPITALIZE, "PICTURE".CAPITALIZE)
.CENTER(COLS * 24 + 4).WRITELN;
WRITELN(YEAR.TEXT.CENTER(COLS * 24 + 4), "\N");
FOREACH (IMMUTABLE R; 0 .. ROWS) {

FOREACH (IMMUTABLE C; 0 .. COLS) {
IF (R * COLS + C > 11)
BREAK;
FOREACH (IMMUTABLE I, LINE; MONS[R * COLS + C])
S[I] ~= FORMAT(" %S", LINE);
}
WRITEFLN("%-(%S\N%)\N", S);
}
}
STATIC THIS() {
PRINT_CALENDAR(1969, 3);
}
Then in another source code file there is a little loader, that imports it and mixes-in it (for safety this program must be compiled with -Jsomepath):
<lang d>import std.string;mixin(import("CALENDAR").toLower);void main(){}</lang>
- Output:

Fortran
Alas, the header "FORTRAN" is not recognised - REAL programmers were absent that day? Even upon the apperance of lower case, I have preferred to use shouting for programme source, and normal upper/lower case for commentary. Aside from petty details such as 1 and l being nowhere as distinct as 1 and L, this allows the two sorts of blather to be identifiably different without ratiocination as the hours drag past. Further, the names of variables can easily be distinguished from the same word in discussion, as in ... the text in TEXT will be printed as the subtitle to the text in TITLE ... Anyway, in the spirit of old, herewith the source without tedious commentary: <lang FORTRAN>

Actual lineprinters offer the opportunity of overprinting lines so double (or triple) printing of the same text gave a bold effect if with some blurring due to wobble. Further decoration was possible: via underlines (and for overlines, an underline on the previous line) the appearance can be improved. Vertical bars can also be used, and more advanced lineprinters (IBM1403 etc. using the "TN" chain) or dot-matrix printers also supplied "corner" glyphs so that boxes would not have leaks.

Icon and Unicon
Icon and Unicon don't lend themselves to REAL programming in the sense of this task easily. And initially this task was marked omit because the primary declarations, reserved words, and the name of the main procedure are all in lowercase. However, getting in the spirit of the task real programmers do not give up and a number of solutions are possible:
- A real programmer could write a preprocessor to eliminate lower case or insert before translation the one unreal line needed to realize this solution
- An uber-real programmer would rewrite the entire translator
- Or, a real programmer could do what's presented below on a coffee break with the preprocessor
In the example,
- we must concede lowercase letters for the preprocessor directive $include (although as noted a preprocessor could handle this)
- we temporarily concede the lowercase letters needed to realize the IPL procedures IsLeapYear and julian; however, a real programmer could easily rewrite these in a more real format (or an uber-real programmer would just rewrite the IPL
- the character set usage has been reduced from 69 unique characters to 51 (within 6 bit character representations) by the following tactics:
- elimination of # and all comments as real programmers don't need them
- use of preprocessor definitions to eliminate the need for {[]}
- use of char (excuse me CHAR) to generate characters such as "\n"
- elimination of tabs for blanks
Now clearly all of these measures will make the storage, interpretation, and comprehension of this program more real and efficient for real programmers like us.
Oh, dear. It seems I have written documentation to explain what I have done. Tisk. Tisk. Someone come take my real programmer epaulettes away. And, you! Since you've read this you must surrender your stripes too.
Also it makes me go all nostalgic for my old WATFIVE compiler. And an IBM 129 keypunch. And 5 hole paper tape.

For added "real"ness, we also only use 1 character names:

(2+[) E '[INSERT SNOOPY HERE]', ":@], D</lang>
B: given a year returns a number which when added to numeric values indexing days that year, mod 7, index the proper day names within a week. (In other words 7 | 0 + B 1969 gives the day of week index for the first day of 1969.)
M: given a year return a list of 12 numbers representing the number of days in each month
R: given a year, return 12 rows of 42 numbers, each row representing days of the month framed in a six week period which will be used to display that month (0 for days that are not part of that month)
H: text that will be the header for each month's block of days
C: A calendar of 12 months (in a flat list, each month is organized text but the months are not yet arranged).
D: given a number of characters (at least 20) and a year, gives the calendar arranged in rows that will best fill that character width without exceeding it.
L: given a textual table (fixed width character columns), left justify it
E: given a textual table and a width, center the text within that width (assuming it fits)
F: width F year gives us our formatted calendar. We do a little extra work here to make sure that a 20 character wide calendar can be displayed. (In that case, we trim off the left and right borders. We use the same trimming code in all cases, but typically we trim empty space added specially for this purpose. That said, the 20 character wide thing seems to be gone from the task description so this definition should be simplified...)
Here's an example calendar (the first line 132 F 1969 being the command that build this calendar):

Note that this version of F will work fine with a left argument of 20 (why anyone felt that this was important to mention is perhaps best thought of as an issue lost in history).
Kotlin
Kotlin is case-sensitive: all its keywords and packages are lower case, all its library classes are mixed case and its library functions are either lower case or mixed case. Consequently, it is impossible to run an upper case version of the Calendar task program as it stands. So what I've done instead (and similar to what several other languages in the same boat have done) is:
1. Saved the Calendar program, after conversion to upper case and a small marked alteration to give upper case output, to a text file called calendar_UC.txt.
2. Written another program called real_calendar.kt which takes calendar_UC.txt as input, outputs a runnable program called calendar_NC.kt to disk, compiles it to a .jar file, runs it, captures the output and prints it to the terminal (Ubuntu 14.04 being used). This program only makes the minimum changes to calendar_UC.txt to enable it to run. Everything else is left as upper case even though almost certainly no Kotlin programmer ("REAL" or not) would write such a program in practice.
This is calendar_UC.txt:

Lua
Tested with Lua 5.3.2
Lua is case sensitive and all the keywords and library routines are in lower case. As with the D sample, we use a simple pre-processor to execute the (slightly modified) upper-cased source of the Lua solution for the standard Calendar task.
The upper case Lua source - stored in a file called UCCALENDAR.LUU:
<lang lua>FUNCTION PRINT_CAL(YEAR)
LOCAL MONTHS={"JANUARY","FEBRUARY","MARCH","APRIL","MAY","JUNE",
"JULY","AUGUST","SEPTEMBER","OCTOBER","NOVEMBER","DECEMBER"}
LOCAL DAYSTITLE="MO TU WE TH FR SA SU"
LOCAL DAYSPERMONTH={31,28,31,30,31,30,31,31,30,31,30,31}
LOCAL STARTDAY=((YEAR-1)*365+MATH.FLOOR((YEAR-1)/4)-MATH.FLOOR((YEAR-1)/100)+MATH.FLOOR((YEAR-1)/400))%7
IF YEAR%4==0 AND YEAR%100~=0 OR YEAR%400==0 THEN
DAYSPERMONTH[2]=29
END
LOCAL SEP=5
LOCAL MONTHWIDTH=DAYSTITLE:LEN()
LOCAL CALWIDTH=3*MONTHWIDTH+2*SEP
FUNCTION CENTER(STR, WIDTH)

ELSE
LINE[I]=STRING.FORMAT("%2D",CURDAY)
END

END

END
RETURN CAL
END
LOCAL CALENDAR={}
FOR I,MONTH IN IPAIRS(MONTHS) DO
LOCAL DPM=DAYSPERMONTH[I]
CALENDAR[I]=MAKEMONTH(MONTH, STARTDAY, DPM)
STARTDAY=(STARTDAY+DPM)%7
END
PRINT(CENTER("[SNOOPY]",CALWIDTH):UPPER(),"\N")
PRINT(CENTER("--- "..YEAR.." ---",CALWIDTH):UPPER(),"\N")
FOR Q=0,3 DO
FOR L=1,9 DO
LINE={}
FOR M=1,3 DO
LINE[M]=CALENDAR[Q*3+M][L]
END
PRINT(TABLE.CONCAT(LINE,STRING.REP(" ",SEP)):UPPER())
END
END
END
PRINT_CAL(1969)
</lang>
The following "one-liner" standard Lua source will down-case and run the program in the source file specified as it's parameter (file luu.lua):
<lang lua>do io.input( arg[ 1 ] ); local s = io.read( "*a" ):lower(); io.close(); assert( load( s ) )() end
</lang>
The following command will execute the UCCALENDAR.LUU source (replace lua532 with the appropriate command for your system):
lua532 luu.lua UCCALENDAR.LUU
- Output:

Perl
Since we can't use eval or print (or any other keywords)
at the top level, we need to abuse backticks in order to print anything, as in the infamous JAPH with no letters or numbers. Consequently, the calendar is printed to standard error instead of standard output.
<lang perl>$PROGRAM = '\'
MY @START_DOW = (3, 6, 6, 2, 4, 0,
2, 5, 1, 3, 6, 1);
MY @DAYS = (31, 28, 31, 30, 31, 30,
31, 31, 30, 31, 30, 31);
MY @MONTHS; FOREACH MY $M (0 .. 11) {
FOREACH MY $R (0 .. 5) {
$MONTHS[$M][$R] = JOIN " ",
MAP { $_ < 1 || $_ > $DAYS[$M] ? " " : SPRINTF "%2D", $_ }
MAP { $_ - $START_DOW[$M] + 1 }
$R * 7 .. $R * 7 + 6;
}
}
SUB P { WARN $_[0], "\\N" } P UC " [INSERT SNOOPY HERE]"; P " 1969"; P ""; FOREACH (UC(" JANUARY FEBRUARY MARCH APRIL MAY JUNE"),
UC(" JULY AUGUST SEPTEMBER OCTOBER NOVEMBER DECEMBER")) {
P $_;
MY @MS = SPLICE @MONTHS, 0, 6;
P JOIN " ", ((UC "SU MO TU WE TH FR SA") X 6);
P JOIN " ", MAP { SHIFT @$_ } @MS FOREACH 0 .. 5;
}
\;
- LOWERCASE LETTERS
$E = '%' | '@'; $C = '#' | '@'; $H = '(' | '@'; $O = '/' | '@'; $T = '4' | '@'; $R = '2' | '@'; $A = '!' | '@'; $Z = ':' | '@'; $P = '0' | '@'; $L = ',' | '@';
`${E}${C}${H}${O} $PROGRAM | ${T}${R} A-Z ${A}-${Z} | ${P}${E}${R}${L}`;</lang> Although, if we are abusing the backticks and other innocent programs, why not just: <lang Perl>$_=$ARGV[0]//1969;`\143\141\154 $_ >&2`</lang>
Perl 6
Uppercase is no challenge, who needs letters at all? [Requires the year to be supplied as a command-line argument, and Unixish cal command.] <lang perl6>$_="\0".."~";< 115 97 121 32 34 91 73 78 83 69 82 84 32 83 78 79 79 80 89 32 72 69 82 69 93 34 59 114 117 110 32 60 99 97 108 62 44 64 42 65 82 71 83 91 48 93 47 47 49 57 54 57 >."$_[99]$_[104]$_[114]$_[115]"()."$_[69]$_[86]$_[65]$_[76]"()</lang>
Phix
OK, I'm not going to take this too seriously but this is as good an opportunity as I'll ever get to showcase how trivial it is to make some rather fundamental changes to the compiler.
So, the first task is to take a copy of Calendar and make it output uppercase. Change the line
<lang Phix>return repeat(' ',left)&s&repeat(' ',right)</lang>
in routine centre to:
<lang Phix>return repeat(' ',left)&upper(s)&repeat(' ',right)</lang>
(That's that done.) Now, Phix is case-sensitive, and many of the keywords and builtins are in lower case, which presents a bit of a challenge - but we can cope.
It is too tedious and not particularly helpful to present a completed solution, instead I shall outline the (relatively simple) steps this would require. I have limited my tests to INCLUDE and INTEGER.
In psym.e you can find the line <lang Phix>initialSymEntry("integer", S_Type,"TI",opInt, E_none) -- #01 / 0b0001 integer</lang> Immediately after that (it should now be there commented out) add: <lang Phix>Alias("INTEGER",symlimit)</lang>
Add similar lines for length, floor, repeat, upper, day_of_week, sequence, string, sprintf, append, printf, join, at the appropriate places.
Keywords are handled slightly differently: In pttree.e we need a new alias routine (you should find this one commented out, from when I was testing all this): <lang Phix>procedure tt_stringA(sequence text, integer alias)
tt_string(text,-2) tt[pcurr] = alias
end procedure</lang> and you can find the line <lang Phix>global constant T_include = 596 tt_stringF("include",T_include)</lang> Sometime after that, in fact after the very last use of tt_stringF, add (likewise you should find this one commented out): <lang Phix>tt_stringA("INCLUDE",T_include)</lang>
Add similar lines for function, end, iff, for, to, do, if, or, then, else, return, procedure, but this time all some ways away from the originals. Quickly run "p p" and make sure you get a normal prompt, without any "T_include should be 624(not 596)" or suchlike.
Currently ptok.e recognises \n but not \N. Search for all references to escchar (there should be one definition and two references) and make sure the character being
checked is mapped to lower case, ie change (twice)
<lang Phix>Ch = find(Ch,escchar)</lang>
to
<lang Phix>Ch = find(lower(Ch),escchar)</lang>
Lastly, the calendar example includes builtins\timedate.e, which contains some lower-case definitions. So copy it to (say) TIMEDATEUPPER.E and change adjust_timedate, timedelta, days (the 2nd param to timedelta), and format_timedate to their uppercase equivalents, and of course change that include to INCLUDE BUILTINS\TIMEDATEUPPER.E.
There is probably some change in ptok.e/pttree.e even simpler than the steps outlined above that makes everything case insensitive, but locating that is left as an exercise for the reader.
You don't actually have to repackage to test this, just run p p test.exw - percentagewise it might be ten times slower (as p.exw is much bigger than test.exw), but it'll still only be a fraction of a second.
Finally, you can take that copy of Calendar and make it all uppercase. In Edita (shipped with Phix) that is just <Ctrl A><Alt U>.
PHP
While PHP functions are case-sensitive (aside of _()), this isn't the case for language constructs.

REXX
This is essentially the same REXX program as for the CALENDAR task, but written entirely in uppercase. Indeed,
it could be written without any Latin (or any language) letters of any kind for the REXX program's variables.
From the task's description, I took it to mean the program was to be in all uppercase, but the output was
still supposed to look pretty (that is, partly in lowercase).
Even so, on the (line) printers that were used
long ago, the printers (if not supporting lowercase),
would print lowercase as uppercase (with the FOLD option).
The other REXX program made use of lowercase letters for determining
the minimum length of any of the options
(from the command line), and a few simple tricks were used to accomplish this.
[Note: the command line may also be all uppercase.]
In any case, both versions of the programs' output are identical
(but the second REXX version sure as heck looks
like it was beat with a big ole ugly stick ─── and pardon the strong language).

CALENDAR - FOR "REAL" PROGRAMMERS
Ruby
UPPERCASE RUBY is normally impossible, because Ruby is sensitive to case, and most methods and keywords have lowercase letters. To solve this task, we wrote a new program loader for UPPERCASE RUBY programs.
Our program loader responds to unknown method calls by calling their lowercase equivalents, so Kernel#PUTS acts like Kernel#puts. Our program loader also defines Object#RESCUE to replace the 'rescue' keyword. We can now write UPPERCASE RUBY programs that call uppercase methods and use no lowercase keywords.
loadup.rbis the program loader.
<lang ruby># loadup.rb - run UPPERCASE RUBY program
class Object
alias lowercase_method_missing method_missing
# Allow UPPERCASE method calls.
def method_missing(sym, *args, &block)
str = sym.to_s
if str == (down = str.downcase)
lowercase_method_missing sym, *args, &block
else
send down, *args, &block
end
end
# RESCUE an exception without the 'rescue' keyword.
def RESCUE(_BEGIN, _CLASS, _RESCUE)
begin _BEGIN.CALL
rescue _CLASS
_RESCUE.CALL; end

Vedit macro language
In Calendar task, standard calendar.vdm macro was called to draw one month calendar. The version here is stand-alone and contains subroutine DRAW_CALENDAR to draw one month calendar.
In addition, short commands are used here. (Normally, long versions of command words are used in RC tasks for readability.) Vedit macro language is case insensitive, but it is normal practice to write short commands in upper case.

XLISP
XLISP isn't case-sensitive, so in principle it would be possible just to reproduce the solution given in the "ordinary" Calendar task. But that program makes use of recursion, "fancy" data structures, long variable names, pretty-printy indentation, and a whole host of other features that I don't think REAL programmers like any better than they like lower case: so, instead, here is a version using only global variables and "DO loops like God meant them to be". <lang lisp>(SETQ YR 1969) (SETQ M #("JANUARY" "FEBRUARY" "MARCH" "APRIL" "MAY" "JUNE" "JULY" "AUGUST" "SEPTEMBER" "OCTOBER" "NOVEMBER" "DECEMBER")) (SETQ ML #(31 28 31 30 31 30 31 31 30 31 30 31)) (SETQ WD #("SU" "MO" "TU" "WE" "TH" "FR" "SA")) (IF (AND (= (REM YR 4) 0) (OR (/= (REM YR 100) 0) (= (REM YR 400) 0))) (VECTOR-SET!

zkl
Using a large helping of grease, in the form of a pre-processor.
The calendar code, file UPCAL.zkl (upper cased version of Calendar#zkl): <lang zkl>VAR [CONST] D=TIME.DATE, DAYS="SU MO TU WE TH FR SA";
FCN CENTER(TEXT,M) { STRING(" "*((M-TEXT.LEN())/2),TEXT) }
FCN ONEMONTH(YEAR,MONTH){
DAY1:=D.ZELLER(YEAR,MONTH,1); //1969-1-1 -->3 (WED, ISO 8601)
DAYZ:=D.DAYSINMONTH(YEAR,MONTH); //1969-1 -->31
LIST(CENTER(D.MONTHNAMES[MONTH],DAYS.LEN()),DAYS).EXTEND(
(1).PUMP(DAYZ,(0).PUMP(DAY1,LIST,T(VOID,""))).APPLY("%2S ".FMT)
.PUMP(LIST,T(VOID.READ,DAYS.LEN()/3,FALSE),STRING.CREATE));
} ...</lang> And the pre-processor, hand rolled for the above code (file bbb.zkl): <lang zkl>code:=File(vm.arglist[0]).read(); code=Data(Void,code.text.toLower()); mixed:=T("string","String", "list","List", " t("," T(",",t(",",T(",
".tostring",".toString", "void.read","Void.Read", "time.date","Time.Date", "utils.","Utils.", "zipwith","zipWith", "daysinmonth","daysInMonth", "monthnames","monthNames", "void","Void", "false","False", "d.october","d.October",
); mixed.pump(Void,Void.Read,'wrap(up,down){ code.replace(up,down) }); Compiler.Compiler.compileText(code)();</lang>
