Is it possible to access environment variables within gpc code, for example $USER ?

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.)

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).
