Someone new to VMS wouldn't start with programs that are at system
level, so it was obvious to me that the reference was to the use of
system services (and I would include the LIB$ in there even though I am
aware there are big differences at how they run, to the average
user-mode programmer, they are just other callable routines).

(Obviously, to someone like Mr VAXman who eats, lives and sleeps in
kernel mode and rarely emerges up to user level, these definitiosn of
"system programming" would be quite different. But there are not many Mr
VAXman's in this universe/reality :-)
