I think someone mentioned WAD. If I remember correctly when using the +1 the

Hi Allan,
AFAIK, mounting the JVM filesystems under /usr/lpp/java/IBM instead of
/usr/lpp/java is *not* standard, but you should of course change the JCL to
match how your installation has it.

Is there a way around this?
Even with SMS-managed GDGs, where the generation is cataloged at
allocation, two jobs that dynamically allocate +1 generations (with GDGNT)
will collide.
For example, from two different jobs:

He'd send a check for any error that you were the first to find. No one
