Assembler Language Coding Workshop

This hands-on classroom laboratory course provides an introduction to the Assembler mainframe language. The course is designed to develop skills appropriate for writing and/or maintaining programs and procedures written in the S/370 or S/390 Assembler language. Emphasis is placed on developing troubleshooting skills by analyzing program control interrupts and reading dumps.

Issues

Recognizing architectural features, such as instruction formats, data representation, storage addressing, etc., that are relevant to program analysis
Identify program breakpoints using a formatted system snapshot and information elements such as Program Status Word (PSW), Instruction Length Code (ILC), underlying program register(s), etc.
Identify appropriate standards for assembler programs in terms of program organization, register conventions, coding practices, documentation, etc.
Coding and debugging assembly language programs that follow standard linking conventions using storage area strings
Define and use different types of data definitions, including fixed-point binary, character, hexadecimal and decimal
Use of standard macros, such as CALL, SAVE, RETURN
Use of various assembler language instructions, such as CSECT, EQU, COPY, END
Use of both symbolic and explicit forms of notation for instructions
Using data literals correctly and explaining the use of LTORG to guide the positioning of a pool of literals
Create and use appropriate patterns for EDIT instructions

Who is this training for?

This intermediate course is designed for application programmers and/or novice system programmers who code, maintain and/or debug application service programs or subroutines written in the S/370 or S/390 assembly language
