Turning On the Trace Facility
Turning On the Trace Facility
There are four ways to turn on the trace facility. In all cases, the trace entries that are
generated depend on settings of the global trace^control^flags (found in the
common^data section of DCCBDECS) and auto^trace^flag (see DEBUGFLAGS on
page 2-54).
DEFINEs for the trace^control^flags are given in Table 2-6 and Table 2-7. As long as
the trace file is open, setting the defined text to 1 causes trace records to be generated
for the corresponding trace class. Setting the defined text to 0 turns off the generation
of trace records for the corresponding trace class. Setting the auto^trace^flag to 1 is
equivalent to turning on all the trace^control^flags for TSCODE and USCODE events.
