Overview

This course provides instruction and practice in the use of the more complex S/390 Assembler Language facilities for the experienced assembler language programmer. The course includes a discussion of standard linkage conventions, use of BSAM/QSAM and selected system macros, the macro definition language, and reentrant coding considerations.

Emphasis is placed on enhancing skills in problem resolution through analysis of more complex system-provided dumps.

Audience

This course is designed for application programmers and beginning system programmers who code, maintain, and debug application support programs or subroutines written in S/390 assembler language.

Skills Gained

Upon completion of this course candidates will be able to:

  • Identify data management considerations and access methods
  • Code assembler language programs which:
    • Conform to standard linkage conventions using save area chaining
    • Define and use BSAM/QSAM datasets through standard I/O macros
  • Define and execute user macros which contain:
    • Positional and/or keyword parameters
    • Fixed or variable entry parameter lists
    • Conditional assembly logic
  • Use variable length storage operations (that is, EX, MVCL, and so on)
  • Employ more complex instructions (that is, TR, TRT, BXLE, and so on)
  • Access JCL parameter data
  • Employ LE date/time handling services
  • Identify reentrant coding considerations and dynamic storage acquisition

Prerequisites

You should be able to code and debug simple S/390 assembler language programs.

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.

Submit an enquiry from any page on this site and let us know you are interested in the requirements box, or simply mention it when we contact you.
