*As(stated*, the answer involves the offspring of the mating of a rhinoceros and an elephand. =GUESSING= that you mean a shell 'envionment variable', the answer is 'yes'. _How_ one can do it depends on the shell (*unspecified*!) being used. 'unsetenv' _may_ do the trick. Alternatively a variable assignment with no value (.e.g "VARIABLE=") may work. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
