According to the manual: "Dynamic PROCLIB can override PROCxx DDs in
the JES2 start PROC but cannot alter nor delete them."

So I decided to try this on a sandbox. It does work and I guess is the
best solution since you don't have to bounce JES2 at all or worry about
the number of converter subtasks etc.

But in playing with it, I found something really interesting (at least to
me).

After I was done adding the dynamic proclib I then deleted the definition
to put me back in a "broken" state. This sandbox JES2 has 2 converter
subtasks and right now one is broke and the other one is still finding the
PROC I am referencing from the proclib I deleted on the original
volume (I allocated one with the same name on another volume).
The interesting thing is that JES2 alternates between the 2 subtasks, so
JES2's usage of them is round robin. Every other job I submit works or
gets a IEC143I 213-04 on the proclib and a IEFC612I PROCEDURE xxx
WAS NOT FOUND error message.
