ISOC Dump Analysis

Overview
This 2 day course is designed to give an introduction to dump analysis in the ISOC environment. The course can be customised to individual customer requirements by including customer dumps, listing and build scripts in the notes and customer dumps for the exercises.

Pre-requisites
The syllabus is designed for TPF developers who have prior TPF 4.1 Dump Analysis experience and understand the layout of a formatted TPF dump. Students should also be proficient in coding programs in ISOC.

Audience
Programmers who are required to read and analyse dumps from programs written using ISOC in a TPF environment

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:

· List the Register usage within an ISOC DLM
· Identify the failing function, and its component within the DLM.
· Use the Listing and Build Script to identify the source code instruction in error.
· Use the Listing to identify variables held in registers vs the stack.
· Locate function stacks within a dump and identify variable values within the stack.
· Identify static variables and global variables in the static stack.
