Generalized Trace Facility Introduction

The Assembler Generalized Trace Facility (GTF) is a debugging tool designed to help speed up the process of isolating the location and cause of a problem in an Assembler program. You use the GTF tool to create a trace file showing the operations performed by the program. You do not have to compile the program for debugging. You can request different levels of detail. For example, you might run a trace requesting program level information and then run a further trace on a specific section by specifying the level of detail and the start and end points for the trace.
