Functions are simple.
code:  procedure ProcedureNameHere
%Code here...
var x, y : int
var prime : array 1 .. 7 of int := init (2, 3, 5, 7, 11, 13, 15)
var a : array 1 .. 7 of int
get x
for i : 1 .. 7
y := 0
loop
if x mod prime (i) = 0 then
x := x div prime (i)
y := y + 1
else
exit
end if
end loop
a (i) := y
end for
for k : 1 .. 7
put a (k)
end for
% end code.
end ProcedureNameHere
% then to call, just type the proc name.
ProcedureNameHere

Simple Simple.

The above poster is wrong, that's actually a procedure, not a function
A function goes
code: 
function whateverthename (place parameters here) : whatever returning value (can be boolean, integer, string, real)
put code here
should end in
result whatever returning value (i.e. result true, result num ... )
end whateverthename

calling it is different than a procedure. You can't just run it normally. For example, if it returned a boolean answer, you would go
code: 
if whatever the name (parameters) = true then

i tried this
code:  function KKK (var x : int) : array 1 .. 7 of int
var prime : array 1 .. 7 of int := init (2, 3, 5, 7, 11, 13, 15)
var a : array 1 .. 7 of int
var y : int
for i : 1 .. 7
y := 0
loop
if x mod prime (i) = 0 then
x := x div prime (i)
y := y + 1
else
exit
end if
end loop
a (i) := y
end for
end KKK
var X : int
get X
put KKK (X) 
but turing said "illegal put item" ???
i dont know where i am wrong

i dunno, I don't really feel like running it but I'm guessing that Turing won't let you have a whole ARRAY as your returning value. I mean, think about it: Turing has NO idea how you want to output or result an array. Do you want to add/catenate the values? Do you want them output on the same line or seperate lines? Ambiguous cases aren't Turing's specialty
also, if you look in your function you never declared "result" and then whatever you wanted. You just put exit. That means that it's supposed to return something, but you're not telling it what.
Change the resulting value, and make sure you have one in your program. If you want to return an array value, that could work, but not the entire array

your program doesnt output anything, it just does some variable changes if some conditions are true, so it would make more sense to make the program a procedure with parameters instead of a function.
