TITLE LOONCE - BLISS-10 COMPILER INITIALIZATION
;FILENAME: LOONCE.MAC
;DATE: 21 DECEMBER 73 CMU/MGM/FLD/KR
; REVISION HISTORY
; 12-29-77 POC TABLE IS EXTENDED TO ADD KI10 INSTRUCTION SET TO
; KA10 INSTRUCTION SET. THE SIZE OF POC TABLE IS ALSO
; INCREASED.
; 5-10-77 CHARACTER TYPE TABLE IS LOADED INTO LOWSEG
; BECAUSE "_" IS AN ALPHACHARACTER IN BLS36C
; AND ASSIGNMENT IN BLISS-10.TYPE TABLE GETS MODIFIED
; UNDER BLS36C SWITCH."_" IS MADE AS ALPHACHARACTER IN
; ROUTINE SWITCHER AND USED IN SKAN ROUTINE.

; BLISS COMPILER "ONCE-ONLY" MODULE
; -------------------------------------
;
; THIS FILE CONTAINS THE CODE TO INITIALIZE THE MAJOR BLISS COMPILER
; TABLES (EG., THE SYMBOL TABLE).IT IS INVOKED ONLY ONCE FOR EACH
; TIME THE COMPILER IS LOADED.
; MANY OF THE VARIABLES DECLARED "EXTERNAL" IN OTHER MODULES ARE
; DEFINED HERE. IN PARTICULAR THE MASTER TABLE, "TABLE", IS DECLARED
; HERE IN SUCH A WAY THAT IT OVERWRITES THE ONCEONLY CODE.

; REVISION HISTORY
; 1/26/77 GLOBAL DLCNT ADDED (NUMBER OF DELETE CHARACTERS FOUND
; IN THE INPUT LINE).
; ADD LOAD& AND LIBRARY& KEYWORDS TO THE SYMBOL TABLE.
