How can we increase the size of an existing PDS to include
more no. of modules.
I tried the answer posted by Jagan(TSO PDS 'pds name') but
did not find it working.
The answer posted by kamal i know very well.
Please suggest me a answer so that we don't need to delete
the existing PDS and still we can change the size as well.

Answer Posted / david

In the old days, (those of us around 70 years old can say
that) there was some "freeware" TSO command called PDS that
was handy for a number of good things. It could increase
the size of a PDS directory without reallocation, but the
PDS dataset needed to have sufficient space to physically
shift members to allow contiguous space for the directory
inside the PDS dataset. This command also had good ISPF
capability (i.e. PDS 'pds.name' ISP), however, as I
remember, the "increase directory" command was TSO only.
Now option 3.4 covers much of that PDS command ISPF
capability.

What are the different rules to perform a Search?

Our issue is there seems to be a disconnect, or no link, between our SELECT statement and our SD. We had SELECT SORT-FILE and SELECT SORT-FILE ASSIGN TO SORTWRK. ASSIGN TO SORTWRK1 SORTWRK2 SORTWRK3 SORTWRK4. with SD SORT_FILE RECORD CONTAINS 7833 CHARACTERS. In either case, at run time, the system ignored our SORTWRK# DD statements and allocated 16 sort works with the SORTWK## naming convention. Any ideas why the system does not recognize the connection? We do not even need the SORTWRK DD statements. Thanks
