Running a variable through a function and a Question

[Mythic Fr0st]

First the question part:

Now in php I would use a function like this (give or take a few mistakes)

function CT (i)
{
if i < 10
set i = "0"+i
return i
}

how would I do this in jass? i've tried im pretty sure the (i) is in the wrong place (Error is "Expected Takes"

function CT (i) takes i returns i
if i < 10
set i = "0"+i
endif
endfunction

Also how would a run a variable though a function like

udg_s = CT(s) or something like that, in PHP

I could do s = CT(s) and it would run through the function and take effect, E.G if s was less than 10, it would show 0 and the value of s, any help plz

and can I have multiple functions in one?

function CT takes nothing returns nothing
blah
function RT takes nothing returns nothing
endfunction
endfunction?

Its late, but lemme take a crack at it. No promises.

function CT takes integer i returns string
local string s = I2S(i)
if i < 10
set s = "0"+s
endif
return s
endfunction


local integer i = 7
set udg_myvar = CT(i)


You cannot have nested functions.


I think that answers all of your questions. GL
