IEF218I

Explanation
In a DD statement, the data set name in the DSNAME
parameter specified either:
A data set that did not exist in the specified volumes.
A model data set control block (DSCB) did not exist on the catalog
volume for a generation data group (GDG) request.

In the message text: jobname
The name of the job.
procstep
The name of the step in the procedure.
stepname
The name of the job step.
ddname
The name of the DD statement.
+ xxx
The relative position of a data set within a concatenation of
data sets, including all data sets implicitly concatenated (through
GDG ALL or OPTCD=B requests). See z/OS MVS JCL User's Guide for
more information on GDG ALL or OPTCD=B requests when used within a
set of concatenated data sets. The first data set of a concatenation
would be +000, but the value +000 is never shown.

System action
The system ends the job.

Programmer response
Check the volume table of contents (VTOC)
for the DSCB specified in the DSNAME parameter on the volume pointed
to by the catalog. If the request is for a generation data group member,
check the catalog volume VTOC for a DSCB for the GDG group. Correct
the error and rerun the job.
