Notes
- All registers not shown above are not used on entry and are preserved
on exit.
- This trap has no equivalent under SMS, probably due to the serious danger of crashing the system.
- The RESPR area is completely removed by this trap - if there are no jobs running - but, as some device drivers allocate RESPR memory, this can cause subsequent system crashes.
- Some versions of QDOS actually allocate more space in the resident procedures area rather than releasing all of it!
- Some things in life are simply best avoided!
