Setting a reg key with variables? And calling with batch?

[-Gamah]

After compiling and running the installer, the GMOD_DIR entry IS MADE IN THE KEY properly, with $R0 and $R1 set and everything.

But when i go to command prompt and type %GMOD_DIR% it tells me that environment variable GMOD_DIR is not defined (though i'm LOOKING AT IT in regedit.exe

any ideas?
