Helper functions and global variables

[Michiel Spape]

Hiya,
Here's one from me:
Function TekenCirkel(xloc, yloc, size as integer, colour as string) as boolean
	cnvsnext.FillColor = CColor(colour)	
	cnvsnext.PenColor = CColor(colour)	
	cnvsnext.Circle xloc, yloc, size
	TekenCirkel = true
end Function

'canvasnext is my buffered canvas, by the way, so at some point you can swap that one for the front one and everything is drawn at once.
...
You get the idea - Function FunctionName (inputvars) as returnvariable-type
Then assign to the functionname. 
All of that you can put in the user area (Alt+5), which is also where all your variables declared are global.

I can't generally be bothered to find out how E-Prime does this sort of thing, so it's quite possible this is not the best way at all. Also, for your convenience, Subs (functions without returns, i.e. voids):

Sub ClrScrNext() 
	cnvsnext.FillColor = CColor(BGColour)
	cnvsnext.clear
End Sub

Cheers,
Mich

Subject: Helper functions and global variables

Hello,
I'm new to e-prime and the last time I did visual basic was 7 years
ago. I am, however, an experienced programmer. Unfortunately I'm stuck
using e-prime on a vista machine, which breaks the help (where I'm
certain I could find the answers to my questions).

How does one go about defining helper functions (functions in an
inline script that can be referred to anywhere in the project) and
global variables (the same but in variable form)? I found the visual
basic syntax for each and tried to just use it inside an inline script
but the compiler threw errors like "Found: Function Expected:
<statement>" for

function foo as integer
return 1
end function

Any help or pointers to good resources besides the help file will be
much appreciated.

Thanks, David
