Records count without using ISREDIT

I have a PS file with huge amount of records in it and I need to get the total number of records using REXX.

I tried using STEM variables, but since it so huge I'm getting Memory allocation error.

Is it possible to get the job done, without using STEM variables and ISREDIT ?

A code snippet for the same would be much helpful.

Regards,
Vamshi

Yes it would be possible, but EXECIO is not a great way to do it as it is quite inefficient for large data volumes.

You could read the file via IEBGENER or SORT, outputting to a dummy file, and then parse the SYSOUT / SYSPRINT output to get the count.

But why do you need to do this, if the creating programs were written correctly this information should already be known.

Of course. Call SORT from rexx.

Here is a topic with some sort cards for counting.

Search here or the web for examples of using Sort from rexx.

You could read one record at a time and count them or read a block of records at a time and accumulate totals. Drop the stem before doing the next read. Still a waste of resource when other utilities can do it much more efficiently.
