PEON

Syntax: PEON [{ #ch | chan_ID | job_name$ }]
Location: PEX

PEX allows buried programs to access the screen in the background.

The PEON command allows you to select which windows and Jobs should allow background screen access.

If no parameter is specified, then background screen access is enabled for all Jobs.  You can however pass any number of parameters, which can be:
1) A SuperBASIC channel number for the current program
2) A QDOS channel number (see CHANNELS) in which case PEX will only affect that specific channel
3) The name of a Job (passed as a string - use a null string ("") for SuperBASIC).  PEX will affect all windows used by that specified Job.

CROSS-REFERENCE:
See PEOFF, PIE_ON, PXON, PEX_INI and IS_PEON for more details.  IS_PTRAP allows you to enable PEX for specific machine code routines.
