COMMON PROGRAMMING ERRORS
1. If the SETSTS monitor call is done for a channel that has not
been initialized, the monitor stops the job and prints:
?IO to unassigned channel at user PC nnnnnn
2. If the data mode is illegal for the device, the monitor
prints:
?Illegal data mode for device xxxnnn; UUO at user PC
nnnnnn
3. Forgetting that bits is an immediate argument, not an address
as in GETSTS.
