Indeed, but too little too late. The OS (not utilities) simplyshould
_never_ change the attributes of an existing nonempty data set.
(Possible exceptions: increasing BLKSIZE, and for RECFM=V increasing
LRECL.) If need be, the programmer can allocate a new data set and copy.
The only time I've used the facility is to recover the mess when someone
has misused it. And then I generally wind up with a PDS containing one
member with RECFM=F among others with RECFM=V. The OS (not whatever
utility) should prevented that happening.
------------------------------<unsnip>----------------------
I disagree strongly. While there are tools that will change dataset
attributes without the use of the OS facilities, the proper solution to
the types of problems you describe is EDUCATION of programmers and the
writers of JCL.
My two cents worth.
