How to read record count thru REXX

amitrath

Hello everyone,

Can anyone tell me how to get the record count of any dataset (whatever dataset type, including VSAM) using rexx. I do not want to open/read the dataset. Is there any variable (say in LISTDSI) where I can read this data.

No code required. Give me the key-word. Thanks in advance.

Thanks Superk for your prompt reply !

If you mean SPACE by 'size', then yes, we can get it from ISPF variables. But ISPF also shows the 'number of records' for any particular dataset in the panels (say =3.4). Is there any way I can find out where does this data come from? ISPF cannot be counting the lines. May be from some ISPF variable?

Thanks again.

May be you are right. ISPF displays the number of records only in case of PDS.

Can you please tell where does this data comes in case of a PDS?

All of that information is retained in the PDS directory.

hy amitrath,

for a ps-file, if you need the exact number of records,
you have to open and read it.

for a pds-file, with SYSDSN you can get the number of members included
in the pds-file SYSMEMBERS, there is a possibility with ispf statistics data, but this won't be available in any case. to be sure you can force the statistics
with ispf-service LMMSTATS...
