   All of the above is correct.  One important note though:  GWBASIC is a
component of MSDOS.  As far as I know, no PS/2's ship with either MSDOS
or GWBASIC.  If your friend is running GWBASIC on a PS/2, make SURE that
he/she has purchased an MSDOS upgrade.  Otherwise, he/she is breaking the
law.  (Note:  I'm not trying to be a smartass, or start a flame war, just
making sure that everyone is aware of licensing and copyright
considerations.)
