REXX or any other utility to edit all the datasets

Dear all,

The mainframe I work on has a maintenance job which deletes all the datasets if they are not referenced in last 5 days. As a
result we loose all our test data regularly and have to do lot of rework. It only happens with sequential files, PDSs are
unaffected.

Is there any rexx or any other utility which can open all sequential files in edit mode starting with a particular high level
qualifier?

Many thanks in advance,
zh_lad

There are ISPF Services (LMDLIST & EDIT, for example) that can do what you want. The problem I see is, what happens when the dataset is too large to be edited?

Hi, Thanks for reading my query and replying. I can certainly go through and help myself. However, can you please let know the particular chapter I need to study? Would it done using JCL or executing a command on command line?

Many thanks.

Try the following JCL to update the dataset's reference date:
