PROMPT command does not work when "ECHO OFF'" but works when
"ECHO ON". These are the lines in the batch file.

ECHO OFF
IF %1 == RED PROMPT $e[41m
IF %1 == GREEN PROMPT $e[42m

If you have a CGA card try it with echo on and off. If you know
the reason why it does not work please let me know. Hope it is
not a bug in 3.1 DOS.
