OBJECTIVES: REXX is a general purpose, high-level, procedural language that can be used for interactive programs and offers significant advantages over older EXEC/EXEC2 (VM) and CLIST (TSO and NetView) interpreted languages. REXX is similar to PL/1 or Pascal in syntax and structure, but has quite a few implementation unique capabilities. This class is available for z/OS and z/VM. Upon successful completion of this course, the student will be able to: - Code REXX instructions with proper syntax. - Construct program logic using REXX control flow instructions. - Invoke and pass parameters to REXX programs. - Code REXX instructions to accomplish file and terminal I/O. - Describe the purpose and use of the data stack. - Write REXX programs that use the data stack. - Use REXX built-in functions to manipulate data. - Create user defined functions and subroutines. - Code REXX instructions that parse complex data strings. - Debug REXX programs using the REXX TRACE facility. - Identify the use of REXX command Environment.
