06D

Explanation
SLIP processing found that an incorrect parameter
list was passed to SLIP.

System action
The system ends SLIP processing for the current
event.  The status of program event recording (PER) in the system
and of the existing SLIP traps is unchanged. The system sends messages
about the problem to the job log.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=06D,ACTION=SVCD,END

System programmer response
Search problem reporting data bases
for a fix for the problem. If no fix exists, try to obtain the ABEND
dump for the abend. If no dump exists, ask the operator to set a SLIP
trap to obtain an SVC dump. Contact the IBM® Support
Center. Provide the dump.
