;	BYTE DEFINITIONS FROM C.MAC.  DEFINE FILE SPEC AREA
;	IN SCNMAC.MAC.
;B)  RESTRICT AC USAGE TO 1-10 (1-4 TEMPS, 5-10 PRESERVED).
;	FLAGS AND MASK MOVED TO CORE.  NAME MOVED TO 7, CHARACTER
;	TO 10.
;C)  INDIRECT I/O REDUCED TO CHANNEL 0 AND READ ONE BLOCK AT A TIME.
;D)  CHARACTER CODING CHANGED TO FOLLOWING:  ESCAPE=0, END OF LINE=-1,
;	END OF FILE=-2.  OCCASIONALLY 200 IS END OF LINE (SAVCHR).
;E)  ALL UUOS AND THEIR BITS, BYTES, AND FUNCTIONS ARE SYMBOLIZED WITH
;	C.MAC.
;F)  CALLING SEQUENCES CHANGED TO BE A BLOCK POINTED TO FROM AC1 TO GIVE

;R)  IMPLEMENT /RUN/RUNOFFSET SWITCHES.
;S)  IN VERB MODE, PERIOD BEFORE VERB SETS STICKY DEFAULTS.
;	CHANGE LOGIC SO VERBS FOR A FILE APPEAR AFTER THE
;	FILES DEFINITION.
;T)  DEFEAT ^O BEFORE TYPING * / OR #.
;U)  IN VERB MODE, ADD NEW MESSAGE
;	? EXCESS ARGUMENTS STARTING WITH ....
;V)  IN VERB MODE, IGNORE LEADING /.  THIS ALLOWS /HELP TO

;X)  GENERALIZE /HELP ARGUMENT TO GIVE SIXBIT PROGRAM NAME
;	(-1 FOR GETTAB 3)  TO USE AS ARGUMENT TO HELPER.

;	FOR ABBREVIATIONS, BUT ON EXACT EQUIVALENCE THE CALLER'S
;	SWITCHES OVERRIDE.
;AH)  ADD MESSAGE: ? AMBIGUOUS SWITCH.
;AI)  IF SWITCH TABLES GIVE NO MAX, THEN ALWAYS GO TO PROCESSOR.
;	IF SWITCH TABLES OMIT POINTER (LH=0), CALL ROUTINE
;	POINTED TO BY RH.
;AJ)  ALLOW KEYWORD SWITCHES TO GET VALUE "0" TO CLEAR INDEX.
;AK)  EXPAND TWO WORD SIXBIT SCAN TO BE MULTIWORD.
;AL)  ADD /HELP:SWITCHES TO LIST ACTUAL SWITCH TABLE.
