Benefits

Students who complete this course will learn to describe the basic elelments of the PL/I language that are different among the PL/I compilers from IBM, in any of their releases (OS PL/I Optimizing Compiler, PL/I for MVS & VM and VisualAge PL/I for OS/390). The student will also learn benefits and implications of using the VisualAge PL/I compiler, and be able to develop applications using the VisualAge PL/I compiler for execution on the mainframe environment.

Audience

PL/I programmers who need to develop new programs with, or migrate existing programs to, the new VisualAge PL/I compiler.

Prerequisites

The student should have experience coding PL/I programs, be comfortable with the text editor you use, and be able to code JCL to run batch jobs.
