- A VMS process gets 1 or more logical name tables and 1 or more symbol tables.
- symbols in VMS are like verbs.
- logical names are like nouns.
- SYS$COMMAND is an alias for your terminal, like stdout in (*)NIX.
- There is a defined heirarchy of tables, like the heirarchy of a (*)NIX file
- system.
-
- SOME of the logical names are no more than global variables like "errno".
-
- SYS$STATUS can be looked at after a DCL ( DEC command language ) operation
- to see if it succeeded. Can't remember more right now, would have to look
- at the proverbial "five-foot shelf of documentation" or the VMS HELP files.
