Monitor Displays
The following can appear on monitor displays to indicate status.
Up to 8 items can be input for monitoring, out of which, 4 will be displayed at any
one time.
An arrow will be displayed in front of status or word contents to indicate you are in
the simple I/O monitor operation and not in the I/O multipoint monitor operation.
Refer to Appendix D Inputs for Instructions and Operands for the key sequences
to specify instructions and operands.
Three examples of monitoring are given below. The first one shows how to moni-
tor multiple items; the second one shows how to change the value of a word in
memory, and the third one shows how to control bit status while monitoring.
