------------------

Bill is right that the "diversity" of ways to do this is a real pain
in the (very low) back. However, the particular method required on
PRIMOS (one which he mentions) is rather trivial, especially when
compared to the nightmarish rigamarole one goes thru on VMS to do
anything!  On Primos one only has to call T1IN which returns a
single character from the user's login terminal. There is a complementary
service which will tell you if there is a character waiting in your
input buffer, but I don't happen to recall its name.
