For some reason DOS 6.0 "CHOICE" feature only allows one choice to be
made per BATCH file.  The first works fine but not any there-after.
The multi-menu feature allows for various configuration changes through-
out the CONFIG.SYS and AUTOEXEC.BAT but limits the number of choices.

KBCLEAR apparently was not made available for DOS 6.0 in mind, but has
proven to be a real benefit to solving the "CHOICE" problem.

To utilize, place the KBCLEAR statement just ahead of the CHOICE state-
ment.  This will clear the keyboard buffer and give "CHOICE" something
new to accept.

Enjoy!
