What You Can Expect
- Develop a better understanding of the machine and how it
processes instructions.
- Develop the skill to write assembler programs, particularly
those small functions which will increase the efficiency
of their corporation's computing throughput.
- Gain a practical introduction to the essential operating
system interfaces with Assembler.
- Enhance their diagnostic skills.
- Improve their dump analysis skills.
- Enhance their ability to use advanced management services.
- Enable themselves to code their own macro definitions
- Enhance their knowledge of Channel Programming and how it
works
- Improve their programmers design abilities
Who Should Take This Course
System Programmers, Technical Support and Software Programmers
and Advanced Application Programmers who need the ability
to write and debug Assembler Language programs and better
understand the software that their installation uses.
Recommended Prerequisites
When attending this Advanced Assembler course, the assumption
is that the person attending will be very familiar with
the instruction set as outlined in the first Assembler
course. Advanced Assembler starts with the understanding
that the first course's instruction set is understood.
The material in Advanced Assembler has substantially increased,
which includes all the new instructions that IBM has made
available. Listed below is the instruction set that we
have traditionally covered. Also, the new instruction
set has been added to this list. Most of the course time
will be handling the remaining instructions that were
not discussed in the first course and the new instruction
set.
Training Style
This class is taught by lecture with hands-on workshops.
