Developing Applications for z/OS UNIX
- Recommended Duration:
- 3 Days
- Version
- z/OS UNIX
- Benefits
- Students who complete this course will be able to create and maintain programs written to run in the z/OS UNIX environment and that use callable z/OS UNIX System Services as well as C functions. They will also be able to construct and use makefiles to support their applications.
- Audience
- Programmers experienced with working in an OS/390 or z/OS environment who will be designing and coding applications that are to be run using z/OS UNIX.
- Prerequisites
- Fundamental knowledge of z/OS UNIX shell scripting such as might be obtained from attending Shell Script Programming in z/OS UNIX, and familiarity with at least one of these programming languages: COBOL, PL/I, C, LE-compliant Assembler.
- Major Topics
-
- Introduction to z/OS UNIX applications
- File access in z/OS UNIX application
- Using QSAM to process HFS files
- Interacting with the user at the OMVS terminal
- Basic printf() and scanf() functions
- Calling C functions from COBOL programs
- Calling C functions from PL/I programs
- Calling C functions from Assembler programs
- Compiling and binding C programs from the shell: c89
- Assembling and binding Assembler programs from the shell: c89
- Compiling and binding COBOL programs from the shell: cob2
- Compiling and binding PL/I programs from the shell: pli
- Callable z/OS UNIX services (BPX1...)
- Parms and environment variables under the shell
- Make and makefiles
- Exercises
- There are 14 machine exercises, although the typical student will only work 8 of them.
