The Data Manipulation instructions are programmed from the industrial
terminal keyboard with the processor in the program mode. When entered,
they are displayed as intensified and blinking, and will continue to blink
until all information is entered.

The default word address, 010, can appear as 3, 4 or 5 digits, depending on
the data table size. When a 4- or 5-digit default address is displayed and a
4- or 5-digit word address is required, the programmer must enter leading
zeros before entering the word address.

Refer to Table 6.A for a summary of the Data Manipulation instructions.
