Hi,
I have a dataset of length 132. For a requirement, I want to read the contents only upto 80th column from it. Is there anyway to do it using ISPF edit macros/REXX?

since zOS I/O is record oriented every read will return a full record
then You are free to process as many bytes as You need

I'm not a REXX expert however, can substring() be of some use here, no - Enrico?

Yes Anuj,
but ...
a generic question just deserves a technically correct but generic answer
really these questions make me wonder if the TS has ever read a manual on the subject

Thanks substring() has helped me.
