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.
