Hi All,

I tried searching the forums for this but was unable to find the solution. I apologize, if this topic has already been discussed and I was not able to find it.

I have a file with first name starting from column 10 till 35.

I have 1000000 records in it.

I also have a subset of 100 members (first name).

Is there a way I can extract these 100 members using a JCL, I do not want to put all the 100 FIRST NAMES in INCLUDE condition.

Hello,

Which sort product is used on your system?

Do you have Easytrieve?

One way to do what you want is to sort both files by first name (making a copy of one or both if the original sequence needs to be preserved) and then "matching" the 2 files writing the "hits" to a file of only the 100 names you want.

To continue -

If this is a one-time requirement and the 100 names are already in a file, it would be easy to create the INCLUDEs with the editor. . .

ranjanp,

If you have SyncSort for z/OS Release 1.2 or higher, I think you can easily do this using a SyncSort JOIN application to extract the matching records.

As asked above, please mention the sort product used in your shop- DFSORT or SyncSort. Also the input LRECL/RECFM.
