TRACE LENGTH
The TRDEF statement establishes the length and name of auser-defined trace. User-defined traces form the
operand of many remote functions in this section. These functions show "TRACE LABEL." as an operand in their
syntax diagrams. Following are some of the functions that operate on user-defined traces.
MIN, TWNDOW
If two traces have different lengths, the largest length is used for the specified span. The shorter length accepts data
until filled.
When a trace of a greater length is operated on and stored in a trace of lesser length, the trace is truncated to fit.
Conversely, when a shorter trace is operated on and stored in a trace of longer length, the last trace element is
extended for operations with the longer length. Thus, a single element trace acts like a display line in trace
operations.
