User spaces would, indeed, not do this.  However, write a couple of your own
API's and it would be transparent.

Put your user spaces in QTEMP.

Pass the user spaces to the submitted job in some manner.

This one's why I suggested QTEMP.  More equitable solutions are available if
this weren't a requirement.

I'd like to hear _that_!  User spaces are not only good, have a 16Mb limit,
and easy to use, but can also be _INDEXED_.  Try it some time...
