SUBTTL THIS ASSEMBLY MADE WITH P.320



;	THE SOURCE TAPE FOR THIS VERSION OF SNOBOL WAS GRACIOUSLY
;	PROVIDED BY BELL TELEPHONE LABORATORIES, HOLMDEL,N.J.
;	THROUGH THE ASSISTANCE OF MR. R.E. GRISWOLD WITHOUT
;	WHOSE HELP THIS PROGRAM WOULD NEVER HAVE BEEN CREATED.
;
;	THE SOURCE TAPE CONTAINS ABOUT 8000 CARD IMAGES OF 
;	IBM/360 MACRO CALLS WHICH ARE USED TO IMPLEMENT
;	SNOBOL. THE MACRO DEFINITIONS FOR THESE CALLS TO ASSEMBLE
;	PROPERLY ON THE PDP-10 ARE CONTAINED IN ANOTHER FILE
;	APPROPRIATLEY CALLED "MACROS".

	; AC DEFINITIONS

;	IN THE FOLLOWING DEFINITIONS SEVERAL RESTIRCTIONS ARE
;	NECESSARY FOR A VARIETY OF REASONS. THEY ARE-
;
;	A1 MUST BE EQUAL TO 1 SINCE IT IS USED TO PASS ARGUMENTS
;	  TO FORTRAN SUBROUTINES.
;
;	A0 MUST REMAIN NOT EQUAL TO 0 SINCE IT IS USED IN THE
;	  INDEX REGISTER FIELD OF MANY INSTRUCTIONS.
;
;	A2,A3,A4 MUST BE CONSECUTIVE AFTER A1 SINCE A PROGRAM
;	IS EXECUTED FROM THESE

;	A10,A11 MUST BE CONSECUTIVE SINCE IN. AND OUT. UUOS
;	ARE EXECUTED FROM THESE FOR REENTRANCY PURPOSES
;
;	Q MUST BE EQUAL TO 16 SINCE IT IS USED WITH THE STANDARD
;	  FORTRAN SUBROUTINE CALLING SEQUENCE.
;
;	P MUST BE EQUAL TO 17 SINCE IT IS ALSO USED WITH THE
;	  STANDARD SUBROUTINE CALLS.
