| Course Abstract: |
This course provides participants the basic skills required to write assembler programs using the IBM High Level Assembler (HLASM). The course introduces participants to the concept and use of assembler languages. Participants learn to use fixed point and decimal (packed) instructions to perform required programming functions. Among the topics to be covered will be:
Character, packed decimal, and binary data instructions
Boolean logic and logical operations
Data editing and output control
Processing tables
Program linkage conventions
Data management macros
Assembler language debugging
Developing large programs using multiple base registers
Creating and using DSECTs |
| Audience: |
This course is designed for individuals who are application and systems programmers that need to develop or maintain programs using the IBM High Level Assembler.
|
| Duration: |
5 days |
| Learning Outcomes: |
Upon completion of this course, the participant will be able to:
> Write high level assembler programs that read and write disk/tape files, and generate formatted reports
> Code, assemble and execute a series of programs using character, logical, packed decimal, and binary data instructions with instructor-supplied JCL and test data
