The hardware page table is a table in memory where the hardware keeps
track of the pages of memory, and includes the storage protection bits
and the NEx bit.  You can see the table entry for a given virtual
address with STRSST like this:

Opt
 1 - Start a service tool
 4 - Display/Alter/Dump
 1 - Display/Alter storage
 2 - Licensed Internal Code (LIC) data
14 - Advanced analysis
select 1 ADDRESSINFO
enter a virtual address, like 1a76b86d3f000000
F10 to page right to see the NEx bit.

neat. thank you.

I don't think changing object type of a *usrspc to *pgm would have any
effect on the NEx bit.

what about changing it from *usrspc to *pgm.  Then save to savf. Then
restore it. The theory being the page table entries are created when an
object is restored to the system. If the system sees the *usrspc as a *pgm,
then it will create the page table entry for that object as executable.
