In a DD statement, a new generation data set was defined to be a VSAM data set, which is not valid. A VSAM data set can be explicitly indicated by the RECORG= keyword, or implicitly defined by a DCB= reference to an existing VSAM data set or by a DCB= backward reference to a prior DD that identifies a VSAM data set. 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 about 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.
