We explore static calls and dynamic calls. How to define variables, structures, and tables is explored, and how to pass these items (by reference, by content, by value) and how to receive them. This includes passing and recieving a variable number of parameters. The class delves into the structure of object code and the workings of the program binder.

Developing Applications for z/OS UNIX Here we move into coding programs that use z/OS UNIX facilities. The course supports Assembler, COBOL, PL/I, and C languages: the students each choose the language(s) they prefer to work in. The programs created can: interact with the user at a terminal, handle files (classic MVS files or z/OS files), and dynamically call subroutines. The programs can be run from the shell or, in some cases, in batch. We cover Assembling / compiling, and binding using z/OS UNIX commands instead of JCL. A deep exploration of make and makefiles allows creating procedures to simplify the maintenance process. (492 pages, appendices, index; 3 days; last updated: 2013)
