This course is designed to enable the student to create, debug, and modify programs in the Open Object REXX (ooRexx) programming language. The course is primarily designed for execution in a Windows environment, although it can also be hosted in a Linux or UNIX (AIX/Solaris) environment.

A principle advantage of Open Object REXX is the ease of creating new programs that utilize existing vendor-supplied and/or site-written classes. Rapid design and development techniques will be taught that result in clean, maintainable code and reusable class libraries.

Before taking this course, students should have attended ProTech’s Multiplatform REXX Programming course or equivalent knowledge of the REXX language keywords, functions and syntax.
