; MODULE DESCRIPTION -
;
;	RST TRACE ROUTINES
;
;	THESE ROUTINES WRITE INTO A FILE MESSAGES TRANSMITTED
;	AND RECEIVED BY THE RST TASK.  TO ENABLE TRACING,
;	THE TRACE LUN MUST BE ASSIGNED TO A DEVICE IN THE
;	TASKBUILD FILE; IF ASSIGNED TO A TERMINAL, MESSAGE
;	LINES WILL BE WRITTEN TO THE TERMINAL.
;
;	THE TRANSMITTED CONFIGURATION MESSAGE IS CANNED, AND
;	SO IS NOT RECORDED, BUT ALL MESSAGES AFTER THAT ARE.
;	A NEW VERSION LEVEL OF THE TRACE FILE WILL BE CREATED
;	EACH TIME THE PROGRAM IS RUN.
