Environment Variables within Code.
Hi, Is it possible to access environment variables within gpc code, for example $USER ? -- Thanks, Andrew McCall Internet/Linux System Administrator I.C.T.

There is a GetEnv function in the module gpc.pas for that purpose. e.g. username:=GetEnv('USER'); also username:=CStringGetEnv('USER'); See gpc.pas in the units directory for the difference.

I think he wants to embed environment variables on the compiling machine in the code.

I don't know what makes you think so (generally I think a program would be more interested to know the user who's running it than who has compiled it), but if so: gpc -DUSER="'$USER'" ... will define USER as a macro (string constant), so something like WriteLn (USER) will work. (This is assuming USER is set, some systems use LOGNAME instead.) Prof A Olowofoyeku (The African Chief) wrote:

Check "getenv" in the DOS unit.
Also in the GPC unit (which is generally preferable to the Dos unit unless you're maintaining BP compatible code).
