Description

This classroom course is designed to teach the student to write Control Language (CL) programs which may be used to perform a variety of system and application control functions. The student will be taught to write basic and intermediate level interactive and batch CL programs, program menus, user commands, and CL programs that function as user tools (programs that use the output of display commands as input).

Audience

This course is intended for application programmers, system programmers and others that have a need to write Control Language programs
