How to get TABLE NAME displayed in SYSPUNCH card.

[Narra]

Hi All,

I am trying to unload some 10 db2 tables from 2 environments and
then do a file comparison between them. Since SYSPUNCH card contains
all the information like field names, column length, position etc, i
have written a Rexx program that reads the SYSPUNCH and does a field
level comparison with the help of length and position fields. Same
way, repeating for the rest of unloaded tables.

Now, my problem is SYSPUNCH card doesn't shows me TABLE NAME (it
simply says SYSREC00) etc.. If i'm able to get them, then in my output
file, i can mention that for table table-name, there were N number of
miscomparisons.

Do we need to code any extra parameter in DSN subprameter of JCL to
get the Table Name, or else it's not possible to do so.

Thanks in anticipation.
Regards,
Narra.
