program EnvironmentTest; { Version 2.0 88/09/15
Demonstrates ENVUNIT.PAS, handy little routines to simplify using the
environment string.
COMPILE TO _DISK_ AND RUN FROM INSIDE THE TURBO INTEGRATED ENVIRONMENT
to simulate nested programs (ie. one program "exec"ed by another).
This program is hereby donated to the public domain. It may be freely copied,
used & modified without charge or fee.
