Tracepoints

Tracing enables information about all block entries and statements to be announced as the program executes. Entry tracing allows an action list to be associated and may be conditional.

There are three pertinent commands to the Trace facility: TRACE, LTRACE, and NTRACE.

• The TRACE command enables statement or entry tracing.
• The LTRACE command lists the current tracing mode.
• The NTRACE command turns off statement or entry tracing.
