T [addr] - Trace User Code This command single step traces program code from the address specified by the PC value, or addr, to the next logical address. Executing the command causes a SWI to be placed at the next executable address(es). If a command macro called TRACE has been defined, it is executed on completion of the T command. A useful Trace macro is: RD DASM * If the next executable instruction involves a branch to the current address, the trace is disabled, to allow the instruction to execute. However, PCbug11 will still display the TRACE state. Since the Talker is interrupt driven, this does not cause any hang-up of the monitor, and all PCbug11 commands are still available.
