COBOL II and COBOL/370 Debugging and Maintenance
- Recommended Duration:
- 2 Days
- Version
- VS COBOL II or COBOL/370.
- Benefits
- Students use VS COBOL II and COBOL/370 facilities for debugging and maintaining programs. The Linkage Editor and Program Binder are discussed extensively.
- Audience
- COBOL II / COBOL/370 programmers who need to know how to code calling and called programs (subroutines) and who need to know how to debug these programs in the MVS/ESA or OS/390 environment; programmers who need to know how to use the Linkage Editor or Program Binder for maintenance.
- Prerequisites
- Basic understanding of the COBOL language, and a working knowledge of how to code JCL statements. Fundamental understanding of CALL statements and subroutine concepts.
- Major Topics
-
- COBOL compiler options, inputs, outputs, and cataloged procedures
- Sources of information
- Anatomy of a COBOL compile listing
- Subroutines and parameters
- Static and dynamic calls
- Linkage Editor and Program Binder
- MVS, OS/390 ABEND dump reading
- Debugging features of the language
- Declaratives
- 31-bit addressing considerations
- Exercises
- There are three standard and one optional hands-on exercises. The exercises in this course may be run on any MVS or OS/390 system using either the VS COBOL II compiler or the COBOL/370 compiler.
