!	RMSSYM.BPR CONTAINS MACROS CALLED IN RMSSYM.MTB.
!	EACH SUCH MACRO IS ALSO DEFINED IN RMSSYM.MPR.
!
!	1. GENERAL PURPOSE INTERNAL MACROS
!	2. VERB AND RMS ERROR DEFINITION
!	3. BLOCK CODES AND BLOCK SIZES
!
!	ALL SYMBOLS DEFINED IN RMSSYM ARE IN THE SCOPE OF USER PROGRAMS.
!	THEREFORE, THE NAMES MUST BE UNDECLARED OR CONVENTIONALLY DEFINED
!	SUCH THAT THEY WILL NOT CONFLICT WITH USER SYMBOLS...
!
!	ALL INTERNALLY USED SYMBOLS SHOULD HAVE $$ SOMEWHERE IN THEIR NAMES.

LITERAL
	V1FABSIZE 	=	16,		! SIZE OF FAB IN R 1
	V1RABSIZE	=	16;		! SIZE OF RAB IN R 1
