8.2 Defining a Temporary Escape Character
The ESC Character may be defined as a temporary as well as a permanent ESC Character.
Below see how to define "%" as a temporary ESC Character.
&&??%
Defining "%" as a temporary ESC Character.
Since the temporary ESC Character is defined in the temporary memory (RAM) alone, it is only in effect as long as the printer is switched on - or until you remove it again. To remove it you define it as "space".
&&??<space>
Removing the temporary ESC Character
NOTE:
For information on how to define a permanent ESC Character, please refer to the 5250 Programmer's Guide; D62079.
