;* NOTE WELL *

;* EOPTAB HOLDS CURRENT OPERANDS ONLY *
;**************************************
;
;
;THE PHASE E STRATEGY IS AS FOLLOWS:
;READ INPUT FROM THE PREVIOUS PHASES STASHING OPERANDS (DISTINGUISHABLE FROM
;OPERATORS BY A 1 IN BIT 0 OF THEIR 1ST WORD) IN EOPTAB (A DYNAMICALLY ALLOCATED
;PUSH-DOWN LIST, WHOSE PRESENT STARTING ADDRESS CAN BE FOUND IN THE RIGHT HALF OF
;EOPLOC) UNTIL AN OPERATOR (BIT 0 OF WORD 1 =0) IS FOUND.
;UPON "SEEING" AN OPERATOR, THE SCANNER ROUTINE WILL CHECK THE OP CODE IN THE
;2ND WORD OF THE ITEM HELD "IN HAND" [W1 & W2 ACCUMULATORS] AGAINST THE HIGHEST
;LEGAL OP CODE KNOWN (ELAST). IF THE OP CODE IS > ELAST, IT CAN BE EITHER
;(A) AN ILLEGAL OP CODE OR (B) THE ENDIT OPERATOR, DENOTING
;END OF INPUT FROM THE PREVIOUS PHASES.
;IF THE OP CODE IS = TO ENDIT, WRAPUP THE CURRENT PHASE, HOUSE CLEANING FILES, ETC.
;AND JUMP TO NEXT PHASE. IF THE OP-CODE FAILS TO BE ENDIT
;AND IS GREATER THAN ELAST, IT IS A BOGUS OP CODE AND AN ERROR MESSAGE IS GIVEN.
;NOTE THAT IN ALL PROBABILITY, A BOGUS OP CODE OF THIS TYPE (> ELAST AND NOT = ENDIT)
;PROBABLY MEANS A COMPILER ERROR.
;IF THE OP CODE IS < OR = ELAST, JUMP THROUGH EOPCOD ENTRY AS SPECIFIED BY
;THE OFFSET WHICH IS THE OP CODE ITSELF TO THE APPROPRIATE SUBROUTINE.
;TO EMEND THE CURRENT SCHEME, ADDITIONS TO THE OP CODE REPERTOIRE SHOULD BE IN THE
;FORM:
; VECTOR <SUBROUTINE ADDRESS>,<FLAGS>
DEFINE VECTOR (PARAM,FLAGS),<
XWD FLAGS,PARAM
EXTERNAL PARAM
>
;COMMONLY USED PARAMETERS ARE ALREADY DEFINED
