Hi,
I have a question regarding file read. I would like to read a VSAM(KSDS) file again after reaching the EOF once. I open & close the file only one time in my program. But there should be repeatative read of the file after reaching EOF eachtime. This should happen more than one time. My mind is not working properly rightnow. Could anyone of you please help on this? Not only VSAM, you can take any file as an example... I think my question is clear. If not, Please feel free to let me know.

Thanks & Regards
CSR

Hi

Once you reached eof, Initialize the key field, put 'start' on the key filed.
(eg. START D-FILE KEY NOT < P-KEY)
read the record.(This is the case if you use ISAM files, But I am not sure about VSAM).

just curious about this

other than a mental challenge. why would you need to do multiple reads after EOF?
