A full trace will display every instruction executed by the program, provided the instruction is in one of the specified tracing regions. It is quite apparent that the volume of output received from such a trace would be prohibitive for a large tracing region; however, if output is queued in lieu of being immediately issued, a full trace can be of much value in revealing the final steps which lead up to an unexpected error condition. For output queuing see "expl trace q" and "expl trace disp".
