Advanced Assembler Language Coding Workshop

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

Issues

Identify data management issues and access methods
Code programs in assembly language that:

Compatibility with standard linking conventions using daisy-chaining of writing areas

Define and use BSAM/QSAM data sets using standard input/output macros
Define and execute user macros that include:

Position and/or keyword parameters

Lists of input parameters of constants or variables
Conditional assembly logic
Using variable-length storage operations (i.e. EX, MVCL, etc.).
Use of more complex instructions (i.e. TR, TRT, BXLE, etc.).
Access to JCL parameter data
Use of date/time service LE
Identifying the issue of reentrant coding and dynamic storage acquisition

Who is this training for?

The course is designed for application programmers and novice system programmers who code, maintain and debug application service programs or subroutines written in the S/390 assembly language
