PL/1 Program Design Techniques


5 hours


The PL/1 Program Design Techniques course builds on the PL/1 Fundamentals course. It explains how to build a structured program in the language. It also describes many of the common built-in functions.


Application programmers who maintain and develop commercial and scientific PL/1 programs


Knowledge of programming concepts and experience with mainframe system architecture


After completing this course, the student will be able to:

  • Define program flow control
  • Define iteration and looping
  • Identify the storage attributes
  • Define built-in functions
