I guess I need to dust off more brain cells. I must obviously have used
DELETE/DEFINE.

Thanks for the suggestions John, but I don't find an IDCAMS ALTER parameter
that allows you to modify the hex device type code for a nonvsam catalog
entry. Am I looking in the wrong place or are you dreaming of the way "it
should be"?
I'd prefer to use something like you suggest but I fail to see a way to make
it work.

Specifically, I am looking for suggestions on what is available for
mass catalog updates. I'd rather not reinvent the wheel if there are
useable tools around.

I don't know of anything in z/OS itself that does this, but perhaps someone
else's product could help. There are at least a couple of companies out
there with catalog management products, I think. And a search of the CBT
site might bear fruit.
Many moons ago, after a similar search for existing tools, I wrote a quick
throwaway program to parse LISTCAT output and build ALTER control statements
for IDCAMS for exactly this purpose. (In our case, some people had used
esoteric names to catalog their data sets using a utility or DYNALLOC--I
forget which--and the catalog entries had to be fixed to move the data sets
to different device types.)
These days I'd think it more sensible to use the Catalog Search Interface to
find the entries needed to build IDCAMS control statements, which would put
a reasonably stable API on both ends of the code. There might be a better
way but that's where I'd tend to start if I had to do it over today. (Well,
actually, I'd start by dusting off the long-unused brain cells I once used
for programming, but...)
