I forget what the JES3 equivalent would be but EXIT 6 in JES2 would be
a simple place to put the code if you wanted to have that feature in
your shop. The specs would be interesting.
1) Clone the card image
2) OC the cloned image with 80X'40' (I do not think any data that
would validly appear on the card except for lower case letters would
be altered) or use a TR with a LC->UC table if you are paranoid.
3) Scan the cloned image for parms that need to be mixed/lower case
(Path= and Parm= for example).
4) Copy the version in the original for these fields into the cloned copy.
5) Optionally also copy comments.
6) Replace the original with the updated cloned copy.
Note: Before step 1, you can do a sanity-check by TRTing for lower
case and bypassing the whole routine if none are found.
I'm sure these specs can be refined but I think they are a good start.
This is not specs. it is rather a proposed implementation of an
incompletely specified function. e.g. step 3.
I admit that I commingled "Here is what needs to be done"
specifications with some "Here is how to do it" implementation
details. The only step that needs expansion to get a full set of
instructions on what needs to be done is step 3 (which you noted)
where I gave a generic description and examples in lieu of listing
each JCL Keyword that can take mixed case parameters as opposed to
needing Upper Case values. The major one a left off was that any
quoted string needs to be reset to its content from the original
copy. Are there any other Keywords that take mixed case (both PARM
and PATH take quoted strings at least in the mixed case situation).
