to a PDS as a PS dataset is almost certainly done by accident. It

It's not an IDCAMS issue.
It's a documented (flaw) feature of JCL.
The first place searched for file attributes is the executing
programme.
If it thinks the file is sequential, it is treated as such.
Ted:
I disagree with you. it is IMO an OPEN issue it should return a RC
that indicates that open was successful but as a sequential dataset.
Although it might break a lot of code its a close call IMO. I think
it revolves around OPEN and a feedback code (which is not presented
to the end user) so IDCAMS is not really at fault its OPEN that has
the flaw, although I can see it from both sides. I can see where IBM
would say BAD and walk away from it, or say its fixed in rel 9999.
Its a no when situation as IBM coded open the way they did and who
knows how much code would need to be fixed? Now if someone had caught
this back in the 60's maybe.. but not this late in the game. On the
other hand they could make IDCAMS (if this is coded in the JCL create
a member called tempname. This might also break programs, but
probably less than the first.
