This operation is used to change the BCD or hexadecimal value of a word
being monitored using the procedure described in 6-2-12 Bit, Digit, Word
Monitor. It is possible in MONITOR or PROGRAM mode only.

Words SR 253 to SR 255 cannot be changed.

Before changing the contents of I/O memory, be sure that the changes will not
cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PC continues to refresh I/O
bits even if the PC is in PROGRAM mode, so devices connected to output points
on the CPU Board or Expansion I/O Boards may operate unexpectedly.

1. Monitor the status of the desired word according to the procedure described

in 6-2-12 Bit, Digit, Word Monitor. If two or more words are being monitored,
the desired word should be leftmost on the display.
