Explanation
A job issued an DEQ macro instruction that included
the TCB  operand. However, the TCB operand identified a task that
was ending.

System action
The system writes a logrec data set error record
and issues an ABEND dump.

System programmer response
  If the problem persists, search
problem reporting data bases for a fix for the problem. If no fix
exists, contact the IBM® Support
Center. Provide the ABEND dump.

Programmer response
Determine why the task identified in the
TCB operand was terminated.  Correct that error and resubmit the job
that caused the abend.
