- Various useful things are stored in the system address space. Many are
- readable by unprivileged users, while others must be accessed from an inner
- access mode. By defining a symbol containing a system space address and
- passing it to the F$FA0 lexical, you can interrogate these addresses and
- format them appropriately.
-
- The best reference for these locations is the VMS Internals and Data
- Structures Manual and the VMS listings kit. You can also poke around in SDA
- after doing a READ SYS$SYSTEM:SYS to load SYS.STB.
-
- Note that accessing these items by address rather than by name can tie
- you to a specific version of VMS - some of them move when things are re-
- linked.
