I think there is one way to do this. Simply copy the
existing PS to another file(give '/' beside the PS and Give
option 17(copy)) It will ask for DSname(give any).
you will get 2 options as below
1. Allocate using same attributes
2. specify your own attributes
select '2' option from the above and change the LRECL as
you need.
now delete the actual file and rename the copied file to
original that's it. your requirement has been met:)
