Structured Programming Macros (SPMs)
Overview
This course will introduce Structured Programming Macros to the
students. These are a tool to help TPF Application Programs written in
Assembler have a more natural programming structure. The generated
machine code is covered to enable students to understand the underlying
machine code when tracing or debugging programs. Some customers use a wider range of SPM's
than listed in the course outline, some prefer fewer. This course can
be customised to reflect your requirements.
Pre-requisites
The students should have experience of coding using BAL.
Audience
TPF Programmers who are required to use SPMs
in their coding.
Student
Numbers
The
maximum recommended student to instructor ratio is 12:1
Objectives
By the end of the course, the delegates will be able, with the aid of
course notes to:
· Code Assembler programs using SPMs
· Use the condensed form of SPMs
· Identify the internal labels used by SPMs
and the machine code generated.
