|Location||SMSQ/E >= 3.12|
Classic versions of the Pointer Environment suspend any jobs that are “buried” in the window stack and try to output onto their window. Some system extensions like PIE, PICE and PEX implemented work-arounds for this, allowing jobs to continue running in the background even with output to the screen.
Starting from version 3.12, SMSQ/E supports background window I/O and update natively. This feature is enabled and disabled by the commands PE_BGON and PE_BGOFF.
Enables background window I/O.
