Using Process Mode Defaults

Device modes and process modes are interdependent. If you change a printer's device mode, its process mode must be compatible (for example, you cannot print PAGE mode data when operating your printer in COMP mode).

You can code the ALTPM= keyword on the DEVICE initialization statement to define which process mode(s) take effect when you change a printer's device mode.

If you do not define alternate process modes and you change a printer's device mode (from MODE=COMP to MODE=FSS or the reverse), JES3 uses default values shown on the following figures.

Table 1. Default Value(s) for ALTPM= When MODE=COMP
Initial process mode value	Default process mode(s) that JES3 uses if you switch to FSS mode	Process mode(s) that JES3 uses if you switch back to COMP mode
LINE	(LINE,PAGE)	LINE
PAGE	(LINE,PAGE)	PAGE
(LINE,PAGE)	(LINE,PAGE)	(LINE,PAGE)

Table 2. Default Values for ALTPM= When MODE=FSS
Initial process mode value	Default process mode(s) that JES3 uses if you switch to COMP mode	Process mode(s) that JES3 uses if you switch back to FSS mode
