 Wow! That directory and the others around it are a real treasure
trove. I found answers to questions I had about calling RTL routines
from Pascal.

For system services and LIB$ (and other RTL) routines, then
I recommend:
General prep:
1) browse through documentation for system services and LIB$
    routines to get an overview
2) learn about the VMS calling convention
3) learn about how to use VMS calling convention
    in your favorite programming language
For specific task:
A) identify the system services and LIB$ routine you need
    to use
B) read the language independent description of how to call it
C) implement call in your favorite programming language
System services:

Is there some introduction to VMS that collects links to resources like
sys$common:[syshlp.examples] where VMS newbies can look to answer their
own questions?

I link to some some stuff at:
