To invoke the Internal Trace Facility the following procedures are required:
- IBM provides a trace control module which must be included
in a load library (on z/OS and CMS), in the standard load module search order,
or in a library in the standard phase search order (on z/VSE),
that is available when the assembly is run. Your IBM support
representative will provide you with the necessary instructions to
perform this procedure.
- Run the assembly with the ITF assembler option. The ITF option
syntax is described below under ITF assembler option.
- Your IBM support representative will advise you of the best
method for providing this material, and of sending it to IBM.
