Description

The TRACE_TABLE option specifies the size of a wrap-around trace table maintained in memory.

The trace table is written when the program ends under the conditions specified by this option.

Tracing is activated, and a trace file is generated, when the MESSAGE_LEVEL option is set to trace.
