The idea of "magic hidden files" might be frowned upon, but I think
that is more due to the description. If you store data for use by
your program in an obscure location, using standard, documented
interfaces I don't see it as a problem. I worry more about software
requiring authorized libraries and software that installs hooks
into system services than software that might store a piece of data
somewhere for its own use.
Andrew:
This is not quite the same but something remotely similar.
A LONG time ago (GT 40) years a vendor who thought he as clever
needed to store a jobname in low memory.
This was fine except MVS needed 2 PSA's (or more) so the the problem
arose that you had to assemble the nuc with a DC of 640" " ((max 80
job names).
At the beginning it was OK. e started having issues when the #'s of
UCB's reached over 1200 (or some number my memory is fuzzy here).
Then to add to the issue the product did not always clear the entry
in the table and it would fill up if we didn't IPL for a few days.
One of the sysprogs had to write a program to see if the job was
still running and if not clear the entry.
We had major management screaming at us as they couldn't order any
more DASD and operations screaming at us because of the JOBNAME issue.
We just old them to talk to the vendor as we didn't write the code. I
think the vendor finally fixed the jobname issue as the problem seem
to disappear after maintenance but the UCB was a PIA for quite some
time as we seemed to be the only customer ho complained.
The vendor as little if any help.
CA bought them out 2 years or so later.
