Suppose we are creating two generations of a GDG in a job.
step1 => +(1)
step2 => +(2)
can variable record lenght GDG be created. If yes any specific option is used?
Let me know the answer of this.. |

GDG can have any type of record formats(FB,VB,..). Even we can catalog two different generations under same GDG base with different properties. |

When talking about GDS it is important to use the correct terminology, as both version and generation are both valid in terms of a GDS.
It is a well known fact that only one version of a GDS may exist at any one time, however, multiple generations may exist together.
Please learn and use the correct terminology when posting, as using the wrong term can cause confusion and possibly delay a resolution to a problem
It would also be interesting to see your idea of mentioning the LRECL in action. Please elaborate. |

Explanation in your post is cryptic, Mukesh. When you say,
Quote: |
can variable record lenght GDG be created |
it can meam two things (for somone from non-english background) 1. Can GDGs have RECFM=VB? 2. Can first GDG have RECFM=FB and other as RECFM=VB, in the same JCL?
DCB information related to any GDG related to "Generation Data Set" and not to the "GDG base". So original question, to start with, does not have any ground - you can have a different DCB info for different GDGs under the same base, but more important question is - why would you like to do that? If that was the requirement, different QSAM files must have been my choice. |
