Know what system is used ?

Hi :)

I'm working on the next IGlass release, but i have a problem :

It's not very easy to update each version for each os ! Exemple
for file requester structur, keyboard, or mouse (one button on mac)

I want only one version... But in the source code a method
to know what os used.example :

If Mac then
XXXX
Endif

If Linux then
XXXX
endif

etc... I have see in the module code some thing like :

?MacOS
Import "-framework AGL"
Import "-framework OpenGL"
?Win32
Import "-lglu32"
Import "-lopengl32"
?Linux
Import "-lGL"
Import "-lGLU"
?

It is the good way to know the used OS ?? can i do :

?Mac
Call something like function
?Linux
Call something like function
?

I have try

Test()

Function Test()
?MacOS
Print "MacOS"
?Linux
Print "Linux"
?Win32
Print "Window"
?
End Function

Seem to work but it is the good way ?

Please help !

Yes. Those compiler directives will help you.

?MAC
Print "I'm ruuning on a Mac"
?WIN
Print "Windows version"
?LINUX
Print "You'll see me in Linux only"
?
Print "I'll show up on all of the systems."

Ok thanks !! Jb :)

Which is it then? ?WIN or ?Win32

Big difference, and I can't find documentation on this...
