ATTENTION: Do not use message control words for any other
purpose. This warning is especially critical for output image
table locations when output or block transfer modules are
placed in corresponding slots. Failure to observe this warning
could result in hazardous or unexpected machine operation.
This could damage equipment and injure personnel.

The message control word file can be located anywhere in the data table
except in processor work areas and in the input image table. If Memory
Write Protect is active, the message control word file must be placed in the
area of the data table which can be changed (words 010-177).

Several keys and special industrial terminal control codes are used to move
through the display and perform a variety of functions (Table 23.D
and Table 23.E).
