This course introduces the REXX instructions used to define and vary program flow, the order in which program instructions execute. Flow control is examined by using keywords to vary the order of execution. Students will examine the ways data can be shared between a calling host environment program and the REXX program which is called, or between a REXX program and a subroutine or function. REXX instructions that support terminal Input/Output (I/O) operations are discussed. REXX facilities for receiving arguments and returning results are analyzed. REXX instructions and interfaces used to read and write information from disk files are also examined. In addition, the Program Stack, buffers, and the use of REXX instructions to control data movement onto and off of a Program Stack are explored. Students will be able to develop a REXX program that accepts arguments on invocation. This course is written to OS/390 2.x. This course is designed as an Introductory level course for automation specialists, system and application programmers, and other individuals who want to create programs in the REXX programming language.
