Hi sureshindira

Use the REPRO command in TSO on the right-most corner we can see number of records processed.




Thanks

what sureshindira told is wrong.
If you want to see no of records are there in any member of PDS then see the size of member(this is the column exists when you open PDS)
without opening member
Here is the example:

Name Prompt Size Created Changed
CBLPGM1 31 2005/04/06 2005/04/06 01:09:04
CBLPGM1R 16 2005/04/06 2005/04/06 01:00:02
COMPILE 34 2005/03/07 2005/03/07 05:09:11
COMPJCL1 63 2005/02/20 2005/04/06 00:49:45
COMPJCL2 65 2005/04/04 2005/04/04 23:00:10
CPYBOOK 5 2005/01/31 2005/02/03 05:27:18
EXCEL 25 2005/01/06 2005/02/11 08:29:48
GDGCRE1 68 2005/01/26 2005/01/26 21:41:50

--------------------------------------------------------------------------
If you want to know no of records in QSAM(PS) file then open the file in browse or view mode....give "m" on command line and press f8 it will go to last record in file....here by seeing last record number you can estimate the number of records exist in QSAM file

As great indian said, you can open any file in browse,edit or view mode. The type 'm' on command line & press 'F8'. You will find the total no of records on the right hand top corner.

Hi,

If you have File-Aid at your site, then you can find the number of records in a flat file using the interactive facility of File-Aid (option 3.8 in File-Aid ver 8.9) and when you are prompted for the function, type 'Tally' to get the number of records. It works much faster than scrolling down to the bottom of the file, particularly when you have millions of records in the file.

Personally, I use a rexx util called COUNTX, which can be used at the DSLIST panel (3.4) as a line command. This is fast enough for most purposes. I had downloaded this from cbttapes. If you want, I can send it to you.

HTH,
Panda.

Hi AshokReddy,

I tried the TSO command you have given as a reply ...

TSO LISTCAT ENT ('MYFILE.RECORDS')

But this is what i get as a result

NONVSAM ------- MYFILE.RECORDS
IN-CAT --- CATALOG.NAME


It did NOT give the number of records in the FILE but it gave Type & Catalog name for the file.
Is there any TSO command by which we can get number of records in the File ?????? This Q? is still not solved.

Thanks

No, there isn't. You'll need to write your own routine.

Kevin,
Thanks for the information. I was hoping that Ashok might be of help here as he has posted before that we can do it, though not correctly.

Thanks
