GetEnvironmentVariable

I'm trying to compile the following code, but max is saying unnexpected \. What's the correct way to do this?

Extern "Win32"
	Function GetEnvironmentVariable(lpName$z, lpBuffer:Byte Ptr, nSize) = "GetEnvironmentVariableA@12"
End Extern

Ah, now I see when I post a thread that the forum has assumed the 'at' symbol was an email address. I just need to remove the slashes that I had seen in other people's code. :P

Totally lost.

Hehe. Basically I'd been trying to use Gellyware's Armadillo functions that use GetEnvironmentVariable, but because it has an @ symbol in the code the forum treats it as an email address and adds slashes to each end. So I was trying to compile code with slashes which shouldn't have been there.

The last solution in this thread from Yan works fine:

Thats much clearer, why cant you just use getenv_()?

Actually GetEnviromentVariable() seems more complex..
