06C

Explanation
One of the following occurred during SLIP processing: While processing a program event recording (PER) interrupt, the
program being monitored issued a Move Character Long (MVCL) instruction
that would overlay low storage.
The environmental indicators that control SLIP processing were
overlaid or not valid for some other reason.

System action
The system ends SLIP processing for the current
event. The status of PER in the system and of the existing SLIP traps
is unchanged.

System programmer response
If the program being monitored caused
the problem, correct the program. If the problem cannot be resolved,
search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center.
