Feed the dataset list into a REXX which generates ISPF edits with an edit macro to do the work. This could even run as an ISPF batch job.
I believe that DF/SORT can also do uppercase translation, if so you need to generate a job to run the SORTs. ISPF skeleton services could do this fairly easily and the skeleton builder could run as an ISPF batch job.
If I use Sort, I create a new dataset name and delete the old, correct?
Willy Jensen - a few postings above - has demonstrated very clearly: SORT can either create a new (copy) dataset, or override the old one. It's up to you.
ISPF EDIT usually makes the updates in-place; but with some tricks it also can create a copy of a dataset.
I have seen IBM advising not to use the same dataset for input and output, but I have done this lots of times over the years without any problems, so it might just be their lawyers speaking.
You can use the job here as a sample of generating the LTOU job using a batch ISPF skeleton builder. The dataset list is referenced by ddname DSLIST in the ISPBAT step. Of course, you could move the members in step 1 to SYSEXEC and ISPSLIB if this has to be done on a regular basis. It also demonstrates some of the lesser know features of skeletons, the ability to use TSO commands and the stack.

We should be clear if the input is all of fixed length or variable. Depending on that, the method has to be chosen. Fixed length, I would chose a SORT PROC, otherwise EDIT MACRO, or whatever the USS hell has spawned to achieve the task (tr/sed/awk..).
