If you mean the DOS environment (programs get their own copy, and
cannot normally change the DOS environment). the answer is yes, but
the technique is tricky and has nothing to do with DJGPP - it's tricky
to do with *any* dos program.  Note that doing this is a FAQ in other
dos programming forums; you can find the generic answer there and port
the technique to djgpp afterwards.
