Assembler Language Coding Workshop

This classroom hands-on lab course provides an introduction to the mainframe Assembler language. The course is designed to develop the skills appropriate to write and/or maintain programs and routines written in S/370 or S/390 Assembler Language. Emphasis is placed on enhancing skills in problem resolution through program check interruption analysis and dump reading.

Objetivos

Recognize architectural features, such as instruction formats, data representation, storage addressing, and so on, which are significant to program analysis
Identify point of program interruption, using the formatted system dump and elements of information such as the Program Status Word (PSW), the Instruction Length Code (ILC), the program’s base register(s), and so on
Identify appropriate standards for assembler programs in terms of program organization, register conventions, coding practices, documentation, and so on
Code and debug assembler language programs which:
Conform to standard linkage conventions using save area chaining
Define and use various types of data definitions, including fixed point binary, character, hexadecimal, and packed decimal
Employ standard macros such as CALL, SAVE, RETURN
Use various Assembler Language statements such as CSECT, EQU, COPY, END
Use both symbolic and explicit notational forms for instructions
Use data literals appropriately, and explain the use of LTORG to direct positioning of the literal pool
Create and use appropriate patterns for EDIT instructions
