I have  noticed a different  behavior (internally) for EXECLOADed  programs on
VM/SP 6 and  VM/SP 5. We are on VM/SP  5 and surely you can 'see'  any file on
the DCSS.  In fact some time  ago I wrote a  small program that would  type or
save to disk a file stored in the DCSS. Again for VM/SP 5 only.
