CodeGolf: FizzBuzz
Let's have a round of CodeGolf!
As usual the goal is to write the shortest solution for a specified problem.
Today we have one of the classics: FizzBuzz.
Write a program that prints the numbers from 1 to 100.
But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.
For numbers which are multiples of both three and five print “FizzBuzz”
To make output a little more readable (and code - more interesting) let's print only one number or word per line, so correct output should be:
It is produced by this unoptimized script:
53 bytes raw
f i=1:1:100 w:i#3=0 "Fizz" w:i#5=0 "Buzz" w:'$x i w !
This is really cool! But the output from this has the integers next to the strings. For example shouldn't:
FizzBuzz90
Instead be:
FizzBuzz
I like it! though $X is a "hack" ;)
That $x thing is awesome. Can't see this solution being beat.
We can save some more bytes:
f i=1:1:100 w $p(i_",Fizz,Buzz,FizzBuzz",",",i#5=0*2+'(i#3)+1),!
"640K ought to be enough for anybody." Oh, I meant, 64 bytes should be enough.
Wow. I think even our Chinese colleagues will not help to read this)
Oh dear! It's incredible!
It depends on, what are the requirements...
Usually we want to occupy as few (RAM) bytes as possible.
Yes, it uses the fewest characters but far more bytes as Robert's solution.
it doesn't show numbers at end
if you run it as single line command in a standard Caché terminal supporting $X,$Y.
newline sets $x=0, $i($Y)
I guess mine doesn't support that! Lol
c'mon - it even works with text files:
I got it working, just needed some dumb troubleshooting and a terminal restart. Cut me some slack! I've never done a code golf before
But a clever one :)

That was my trigger. Thanks @Eduard Lebedyuk for the hint
It also requires Unicode, it won't work on a 8-bit installation.
No, it works and all installations but yes, it needs 8 Bit characters.
A simple command like
write "abcd"
writes out four 8-Bit characters, independent of your installation (8-Bit or Unicode)
On Evgeny Shvarov's PC, a command like
write "Физз"
would write out four 16Bit characters, in sum 2*4 = 8 characters, each with 8 Bits
It needs Unicode characters as well, otherwise it fails. Just compare 8 bit instance run:
with Unicode one:
67 bytes raw
f i=1:1:100 w $s(i#15=0:"FizzBuzz",i#3=0:"Fizz",i#5=0:"Buzz",1:i),!
My one)
I think shortest one will be :
USER>f i=1:1:100 w !,$S(('(i#3)&'(i#5)):"FizzBuzz",'(i#3):"Fizz",'(i#5):"Buzz",1:i)

Not the smallest, but shortest -- 42 characters. Based on Robert's answer.
I think you will find this is as short as it can possibly go before it starts to become unmaintainable...
fizzbuzz
f ii=1:1:100 {
s i=$tr($t(words+$s(ii#15=0:1,ii#3=0:2,ii#5=0:3,1:4)),"; ")
i i="ii" s i=@i
w !,i
