It's certainly possible to have DSORG=PS,RECFM=U data set that does not
contain load modules.  I've used them.  I believe it's also possible to
have DSORG=PO,DSNTYPE=PDS,RECFM=U with content other than load
modules, but ISPF refuses to recognize this fact.  I don't know whether
DSORG=PO,DSNTYPE=LIBRARY,RECFM=U can have content other than
program objects.  I understand no PDSE can contain a mixture of program
objects and other members.

It has been announced that in 2.1 Rexx EXECIO will support RECFM=U.
When we get 2.1 I'll need to experiment to discover the restrictions.
