 Posted: Wed Oct 29, 2003 10:48 am Post subject: Is there a utility to generate copybooks from a load module? |
 |
|
Hello all,
Is there any utility available that can take a load module and generate the copybooks for VSAM files that were used in the programs? I not only want to know the record length at the time, I also want to know the columns? Is this possible?
For example, I am missing a copy layout of a VSAM dataset we have in our shop. I need to determine the record layout for the file at a specific point in time using the load module of a program that reads/writes to the dataset.
Thanks |

Sorry, no. The load module doesn't contain any info about the record layouts. It would be an impossible job for a program to analyze the machine instructions in a load module and try to figure out the size and type of record field. |

Can't you just look at the source and see the file definition? Am I missing something here?
Do you mean to say that you just have a loadlib but you lost your source??

Hi,
While you can't use a load module to get copybook data, your shop my keep back (archival) versions of your production pgms. If so recompile the appropriate version in the test environment to get the info.
