     Using the keymatrix function sounds like a valid way of dealing with
auto-repeat, and dealing with auto-repeat to avoid run on is certainly a valid
thing to do (understatement of the year, I HATE programs that don't properly
deal with auto-repeat).

     However, I happen to use a different method.  Psuedo code is:

;     if (AuxValid)           /* If a previous message is cached */
;         Copy AuxMessageBuffer to MessageBuffer
;     else
;         if GetMsg()
;             {
;             Copy message to MessageBuffer
;             Reply to message.
;             }
;         else
;             Exit(FALSE);
;     AuxValid = FALSE.
;     /* now deal with auto-repeat. */
; StillAutoRepeating:;
;     while (GetMsg)
;         {
;         Copy message to AuxMessageBuffer
;         if (AuxMessageBuffer.Qualifier & IEQUALIFIER_REPEAT)
;             goto StillAutoRepeating;
;         else
;             {
;             AuxValid = TRUE;
;             Exit(TRUE);
;             }
;         }
;     Exit(TRUE);
;
;         If this routine returns true, look for a message in MessageBuffer.

     Basically, after getting a message, keep reading message until you run out
of messages or until you read in a message that doesn't have the auto-repeat
bit set.  Cache the last message read so that you can use it next time.  It
works.
