! $MESSAGE
! =======

! THIS ROUTINE PROCESSES THE $MESSAGE MACRO.
!	THE $MESSAGE MACRO CONTROLS THE ACTIONS WHICH RMS-20
!	TAKES WHEN A FILE CONSISTENCY ERROR OR AN INTERNAL
!	LOGIC ERROR IS DISCOVERED. IF THE $MESSAGE MACRO HAS
!	BEEN EXECUTED, AN ERROR MESSAGE WILL BE PRINTED OUT ON
!	THE USER'S TERMINAL. IF THE $NOMESSAGE MACRO HAS BEEN
!	EXECUTED, NO ERROR MESSAGE IS TYPED. IN BOTH CASES,
!	AN ERROR RETURN TO THE USER IS TAKEN.
!	WHEN RMS-20 IS INITIALLY LOADED, THE DEFAULT ACTION
!	IS TO ENABLE ERROR MESSAGES

! $NOMESSAGE
! ==========

! THIS ROUTINE PROCESSES THE $NOMESSAGE MACRO.
!	IF THE $NOMESSAGE MACRO IS EXECUTED, ALL ERROR MESSAGES
!	WILL BE SUPPRESSED BY RMS-20. HOWEVER, AN ERROR RETURN
!	TO THE USER WILL STILL BE TAKEN.
!
!	NOTE THAT NO CHECK IS MADE TO DETERMINE THE PRESENT STATE
!	OF THE "NOMESSAGE" STATUS BIT. THUS, TWO SUCCESSIVE
!	$NOMESSAGE MACROS WILL SUCCEED.
