On a Windows system at the command prompt if you type in the command SET This will display a list of environment variables available on the system and accessible via $ENV{'%variable%'} %SystemDrive% == $ENV{'SystemDrive'} %SystemRoot% == $ENV{'SystemRoot'} This is standard across windows platform (now I cant confirm this for Windows 95,98, me)

Sent by: perl-win32-users-boun...@listserv.activestate.com I discovered (on my computer) that ENV vars named ?SystemRoot? and ?SystemDrive? exist. Does anyone know if these would be present on all Windows computers? If so, it would seem the answer here would be to merely look at $ENV{?SystemDrive?} Can anyone think of a reason where these ENV vars would not exist?
