C  ------  -------------------------------------------------------------
C              I M P L E M E N T A T I O N    N O T E S
C              - - - - - - - - - - - - - -    - - - - -
C    THE PL/M COMPILER IS INTENDED TO BE WRITTEN IN ANSI STANDARD
C    FORTRAN - IV, AND THUS IT SHOULD BE POSSIBLE TO COMPILE AND
C    EXECUTE THIS PROGRAM ON ANY MACHINE WHICH SUPPORTS THIS FORTRAN
C    STANDARD.  BOTH PASS-1 AND PASS-2, HOWEVER, ASSUME THE HOST
C    MACHINE WORD SIZE IS AT LEAST 31 BITS, EXCLUDING THE SIGN BIT
C    (I.E., 32 BITS IF THE SIGN IS INCLUDED).
C
C    THE IMPLEMENTOR MAY FIND IT NECESSARY TO CHANGE THE SOURCE PROGRAM
C    IN ORDER TO ACCOUNT FOR SYSTEM DEPENDENCIES.  THESE CHANGES ARE
C    AS FOLLOWS
C
C    1)   THE FORTRAN LOGICAL UNIT NUMBERS FOR VARIOUS DEVICES
C         MAY HAVE TO BE CHANGED IN THE 'GNC' AND 'WRITEL' SUBROU-
C         TINES (SEE THE FILE DEFINITIONS BELOW).
C
C     2)   THE HOST MACHINE MAY NOT HAVE THE PL/M 52 CHARACTER SET
C           0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ$=./()+-'*,<>:;
C         (THE LAST 15 SPECIAL CHARACTERS ARE
C         DOLLAR,  EQUAL,  PERIOD,  SLASH, LEFT PAREN,
C         RIGHT PAREN, PLUS,   MINUS,  QUOTE, ASTERISK,
C         COMMA, LESS-THAN, GREATER-THAN, COLON, SEMI-COLON)
C         IN THIS CASE, IT IS NECESSARY TO CHANGE THE 'OTRAN' VECTOR IN
C         BLOCK DATA TO A CHARACTER SET WHICH THE HOST MACHINE SUPPORTS
C
C     3)   THE COMPUTED GO TO IN 'SYNTH' MAY BE TOO LONG FOR SOME
C         COMPILERS.  IF YOU GET A COMPILATION ERROR, BREAK THE
C         'GO TO' INTO TWO SECTIONS.
C
C     4)  THE HOST FORTRAN SYSTEM MAY HAVE A LIMITATION ON THE NUMBER
C         OF CONTIGUOUS COMMENT RECORDS (E.G. S/360 LEVEL G). IF SO,
C         INTERSPERSE THE DECLARATION STATEMENTS INTEGER I1000, INTEGER
C         I1001, ETC., AS NECESSARY TO BREAK UP THE LENGTH OF COMMENTS.
C         THE SYMBOLS I1XXX ARE RESERVED FOR THIS PURPOSE.
C
C    THERE ARE A NUMBER OF COMPILER PARAMETERS WHICH MAY HAVE TO
C    BE CHANGED FOR YOUR INSTALLATION.  THESE PARAMETERS ARE DEFINED
C    BELOW (SEE 'SCANNER COMMANDS'), AND THE CORRESPONDING DEFAULT
C    VALUES ARE SET FOLLOWING THEIR DEFINITION.  FOR EXAMPLE, THE
C                  $RIGHTMARGIN = I
C    PARAMETER DETERMINES THE RIGHT MARGIN OF THE INPUT SOURCE LINE.
C    THE PARAMETER IS SET EXTERNALLY BY A SINGLE LINE STARTING WITH
C    '$R' IN COLUMNS ONE AND TWO (THE REMAINING CHARACTERS UP TO
C    THE '=' ARE IGNORED).  THE INTERNAL COMPILER REPRESENTATION
C    OF THE CHARACTER 'R' IS 29 (SEE CHARACTER CODES BELOW), AND THUS
C    THE VALUE OF THE $RIGHTMARGIN PARAMETER CORRESPONDS TO ELEMENT 29
C    OF THE 'CONTRL' VECTOR.
C
C     1)  THE PARAMETERS $T, $P, $W, $I, $O, AND $R
C        CONTROL THE OPERATING MODE OF PL/M.  FOR BATCH PROCESSING,
C        ASSUMING 120 CHARACTER (OR LARGER) PRINT LINE AND 80 CHARAC-
C        TER CARD IMAGE, THE PARAMETERS SHOULD DEFAULT AS FOLLOWS
C                $TERMINAL   =  0
C                $PRINT      =  1
C                $WIDTH      = 120
C                $INPUT      =  2
C                $OUTPUT     =  2
C                $RIGHTMARGIN= 80
C        NOTE THAT IT MAY BE DESIRABLE TO LEAVE $R=72 TO ALLOW ROOM
C        FOR AN 8-DIGIT SEQUENCE NUMBER IN COLUMNS 73-80 OF THE PL/M
C        SOURCE CARD.
C
C    2)  FOR INTERACTIVE PROCESSING, ASSUMING A CONSOLE WITH WIDTH
C        OF 72 CHARACTERS (E.G., A TTY), THESE PARAMETERS SHOULD
C        DEFAULT AS FOLLOWS
C                $TERMINAL   =  1
C                $PRINT      =  1
C                $WIDTH      = 72
C                $INPUT      =  1
C                $OUTPUT     =  1
C                $RIGHTMARGIN= 72
C
C    3)  THE CHARACTERISTICS OF THE INTERMEDIATE LANGUAGE FILES
C        PRODUCED BY PASS-1 ARE GOVERNED BY THE $J, $K, $U, $V, AND
C        $Y PARAMETERS.  THESE PARAMETERS CORRESPOND TO THE DESTINATION
C        AND WIDTH OF THE INTERMEDIATE CODE FILE ($J AND $K), AND
C        DESTINATION AND WIDTH OF THE INTERMEDIATE SYMBOL TABLE ($U
C        AND $V).  SOME FORTRAN SYSTEMS DELETE THE LEADING CHARACTER
C        OF THE FILES PRODUCED BY OTHER FORTRAN PROGRAMS.  THE $Y
C        PARAMETER CAN BE USED TO PAD EXTRA BLANKS AT THE BEGINNING OF
C        THE INTERMEDIATE FILES IF THIS BECOMES A PROBLEM ON THE HOST
C        SYSTEM.
C
C        UNDER NORMAL CIRCUMSTANCES, THESE PARAMETERS WILL NOT
C        HAVE TO BE CHANGED.  IN ANY CASE, EXPERIMENT WITH VARIOUS
C        VALUES OF THE $ PARAMETERS BY SETTING THEM EXTERNALLY BE-
C        FORE ACTUALLY CHANGING THE DEFAULTS.
C
C    THE IMPLEMENTOR MAY ALSO WISH TO INCREASE OR DECREASE THE SIZE
C    OF PASS-1 OR PASS-2 TABLES.  THE TABLES IN PASS-1 WHICH MAY BE
C    CHANGED IN SIZE ARE 'MACROS' AND 'SYMBOL' WHICH CORRESPOND TO
C    THE AREAS WHICH HOLD 'LITERALLY' DEFINITIONS AND PROGRAM SYMBOLS
C    AND ATTRIBUTES, RESPECTIVELY.  IT IS IMPOSSIBLE TO PROVIDE AN
C    EXACT FORMULA WHICH RELATES THE NUMBER OF SYMBOLS HELD BY EITHER
C    OF THESE TABLES TO THE TABLE LENGTH, SINCE TABLE SPACE IS DY-
C    NAMICALLY ALLOCATED ACCORDING TO SYMBOL NAME LENGTH AND NUMBER
C    OF ATTRIBUTES REQUIRED FOR THE PARTICULAR SYMBOL.
C
C    1)  IN THE CASE OF THE MACROS TABLE, THE LENGTH IS RELATED TO THE
C        TOTAL NUMBER OF CHARACTERS IN THE MACRO NAMES PLUS THE TOTAL
C        NUMBER OF CHARACTERS IN THE MACRO DEFINITIONS - AT THE DEEP-
C        EST BLOCK LEVEL DURING COMPILATION.  TO CHANGE THE MACRO
C        TABLE SIZE, ALTER ALL OCCURRENCES OF
C
C                         MACROS(500)
C
C        IN EACH SUBROUTINE TO MACROS(N), WHERE N REPRESENTS THE NEW
C        INTEGER CONSTANT SIZE.  IN ADDITION, THE 'DATA' STATEMENT
C        BLOCK DATA (LAST PROGRAM SEGMENT) MUST BE CHANGED FOR THE
C        MACRO PARAMETERS BASED UPON THE CONSTANT VALUE N TO
C
C           DATA MACROS /N*0/, CURMAC /N+1/, MAXMAC /N/,
C          1    MACTOP /1/
C
C    2)  IF THE IMPLEMENTOR WISHES TO INCREASE OR DECREASE THE SIZE
C        OF THE SYMBOL TABLE, THEN ALL OCCURRENCES OF
C
C                          SYMBOL(4000)
C
C        MUST BE CHANGED TO SYMBOL(M), WHERE M IS THE DESIRED INTEGER
C        CONSTANT SIZE.  THE 'DATA' STATEMENTS FOR SYMBOL TABLE PARA-
C        METERS MUST ALSO BE ALTERED AS DESCRIBED IN THE CORRESPONDING
C        COMMENT IN BLOCK DATA.  IN PARTICULAR, THE LAST ITEM  OF
C        THE DATA STATEMENT FOR 'SYMBOL' FILLS THE UNINITIALIZED POR-
C        TION OF THE TABLE WITH ZEROES, AND HENCE MUST BE THE EVALUATION
C        OF THE ELEMENT
C                           (M-120)*0
C
C        (IT IS CURRENTLY (4000-120)*0 = 3880*0).  THE DATA STATEMENT
C        FOR MAXSYM AND SYMABS MUST BE CHANGED TO INITIALIZE THESE
C        VARIABLES TO THE VALUE M.
C
C    GOOD LUCK...

C     THE '48' USED IN BLOCK INITIALIZATION AND IN SYMBOL TABLE
C     INITIALIZATION IS DERIVED FROM THE PROGRAM 'SYMCS' WHICH
C     BUILDS THE INITIAL SYMBOL TABLE.  IF THIS NUMBER CHANGES, BE
C     SURE TO ALTER 'BLOCK', 'BLKSYM', 'SYMTOP', AND 'SYMCNT'.
C     TWO ARRAYS, SYM1 AND SYM2, ARE EQUIVALENCED OVER THE
C     SYMBOL TABLE ARRAY IN ORDER TO LIMIT THE NUMBER OF
C     CONTINUATION CARDS IN SYMBOL TABLE INITIALIZATION
C     BELOW.  THE LENGTHS OF SYM1 AND SYM2, THEREFORE, MUST
C     TOTAL THE LENGTH OF THE SYMBOL TABLE.  CURRENTLY, THESE
C     ARRAYS ARE DECLARED AS FOLLOWS
C
C         SYM1(60) + SYM2(3940) = SYMBOL(4000)
C
C     IF YOU INCREASE (DECREASE) THE SIZE OF SYMBOL, YOU MUST
C     INCREASE (DECREASE) THE SIZE OF SYM2 AS WELL.
C
C     NOTE ALSO THAT THE REMAINING ENTRIES OF THE SYMBOL
C     TABLE ARE SET TO ZERO AT THE END OF THE DATA STATEMENT
C     FOR SYM2.  CURRENTLY, THIS IS ACCOMPLISHED WITH THE LAST
C     ENTRY IN THE DATA STATEMENT
C

C
C     AGAIN, IF YOU CHANGE THE SIZE OF SYMBOL, YOU MUST
C     ALSO CHANGE THIS LAST ENTRY.  IF FOR EXAMPLE, YOU ALTER
C     THE SIZE OF SYMBOL TO 3000, THE LAST ENTRY 1880*0 BECOMES
