This course is intended to quickly bring the application programmer up to speed in an OpenVMS environment. The scope of material is fairly broad – from basic compiling to advanced system services. Although some of the material will be provided as an exposure to capabilities available to the programmer, it is expected that the students will be able to program at an in-depth level upon completion of this course.

Prerequisites

OpenVMS Fundamentals and OpenVMS System Management I or equivalent experience as well as fundamental understanding on system concepts.

Course Objectives

Upon completion of the course, students should be able to:

  • Compile and link a program
  • Read listing and map files
  • Understand how to call system procedures, including system services and runtime library routines
  • Create a process
  • Communicate with another process
  • Synchronize using event flags, mailboxes, global sections, and locks

Course Audience

OpenVMS applications programmers
OpenVMS system programmers
