   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
