1FC

Explanation
In response to a Supervisor Call (SVC) instruction,
the SVC first level interrupt handler (FLIH) was running, but a system
error occurred.

System action
In an attempt to recover, the system abnormally
ends the task that issued the SVC instruction. The system writes a
logrec data set error record.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=1FC,ACTION=SVCD,END

System programmer response
Do the following: Find the original abend causing the problem in the system diagnostic
work area (SDWA) in the logrec data set error record for abend X'1FC'.
Search problem reporting data bases for a fix for the problem.
If no fix exists, ask the operator to set a SLIP trap to obtain an
SVC dump. Contact the IBM® Support
Center. Provide the SVC dump and, if available, the logrec data set
error record.
