WA1877 Basic Assembler Language Programming Training and Courseware
|
|
This course introduces students to the basic skills required to write assembler programs using the IBM High Level Assembler (HLASM).
Students will code Assembler programs with the following capabilities –
- Use Character, packed and binary data instructions
- Edit input data and build output reports
- Processing data in tables
- Build program linkage
- Code data management macros
- Use dumps to debug Assembler language program S0C7 abends
- Developing larger programs using multiple base registers
- Creating and using DSECTs.
Students will code, assemble and execute a series of programs using fixed point and decimal instructions and file access. |
