SUBROUTINE DAPATH(LOWVLU,KNTVLU,IVALUE,JSTIFY,IFILL ,

C RENBR(/REPRESENT INTEGER SEQUENCE OF FORM 1.2.3)
C
C DONALD BARTH, HARVARD BUSINESS SCHOOL
C
C LOWVLU = SUBSCRIPT OF LOWEST LOCATION IN IVALUE ARRAY
C WHICH SPECIFIES PART OF INTEGER SEQUENCE TO
C BE REPRESENTED.
C KNTVLU = SUBSCRIPT OF HIGHEST LOCATION IN IVALUE
C ARRAY WHICH SPECIFIES PART OF INTEGER
C SEQUENCE TO BE REPRESENTED.
C IVALUE = ARRAY CONTAINING DESCRIPTION OF INTEGER
C SEQUENCE IN LOCATIONS IVALUE(LOWVLU) THROUGH
C IVALUE(KNTVLU). VALUES EQUAL TO OR GREATER
C THAN ZERO ARE REPRESENTED DIRECTLY AND
C SEPARATED BY PERIODS. VALUES LESS THAN ZERO
C ARE NOT REPRESENTED, BUT SAME SEPARATING
C PERIODS APPEAR AS IF VALUES WERE
C REPRESENTED.
C JSTIFY = -1, LEFT JUSTIFY REPRESENTATION OF INTEGER
C SEQUENCE IN FIELD CONSISTING OF
C IBUFFR(LFTCOL+1) THROUGH IBUFFR(LFTCOL+
C IWIDTH).
C = 0, CENTER REPRESENTATION OF INTEGER SEQUENCE
C IN FIELD CONSISTING OF IBUFFR(LFTCOL+1)
C THROUGH IBUFFR(LFTCOL+IWIDTH). IBUFFR ARRAY
C LOCATIONS TO LEFT OF REPRESENTATION OF
C INTEGER SEQUENCE ARE FILLED WITH SPACES.
C = 1, RIGHT JUSTIFY REPRESENTATION OF INTEGER
C SEQUENCE IN FIELD CONSISTING OF
C IBUFFR(LFTCOL+1) THROUGH IBUFFR(LFTCOL+
C IWIDTH). IBUFFR ARRAY LOCATIONS TO LEFT OF
C REPRESENTATION OF INTEGER SEQUENCE ARE
C FILLED WITH SPACES.
C IFILL = 0, DO NOT FILL PORTION OF FIELD RIGHT OF
C REPRESENTATION OF INTEGER SEQUENCE WITH
C SPACES. VALUE OF IFILL HAS NO EFFECT ON
C PRINTING CHARACTERS IN REPRESENTATION OF
C INTEGER SEQUENCE. KOUNT WILL BE RETURNED
C POINTING TO RIGHTMOST PRINTING CHARACTER IN
C REPRESENTATION OF INTEGER SEQUENCE.
C = 1, FILL FIELD RIGHT OF REPRESENTATION OF
C INTEGER SEQUENCE AND EXTENDING THROUGH
C IBUFFR(LFTCOL+IWIDTH) WITH SPACES. KOUNT
C WILL BE RETURNED RETURNED POINTING TO
C IBUFFR(LFTCOL+IWIDTH).
C IWIDTH = WIDTH, STATED AS NUMBER OF COLUMNS OR IBUFFR
C ARRAY LOCATIONS, OF FIELD IN WHICH INTEGER
C SEQUENCE IS TO BE REPRESENTATED. RIGHTMOST
C IBUFFR ARRAY LOCATION IN FIELD HAS SUBSCRIPT
C LFTCOL+IWIDTH OR ELSE MAXBFR, WHICHEVER IS
C SMALLER.
C LFTCOL = SUBSCRIPT OF IBUFFR ARRAY LOCATION TO
C IMMEDIATE LEFT OF LEFTMOST IBUFFR ARRAY
C LOCATION INTO WHICH EITHER SPACE OR
C CHARACTER OF REPRESENTATION OF INTEGER
C SEQUENCE CAN BE PLACED.
C MAXBFR = SUBSCRIPT OF RIGHTMOST IBUFFR ARRAY LOCATION
C WHICH COULD BE PLACED SPACE OR CHARACTER OF
C REPRESENTATION OF INTEGER SEQUENCE IF IWIDTH
C IS LARGE ENOUGH.
C IBUFFR = ARRAY IN WHICH REPRESENTATION OF INTEGER
C SEQUENCE IS RETURNED, 1 CHARACTER PER ARRAY
C LOCATION AS THOUGH READ BY MULTIPLE OF A1
C FORMAT.
C KOUNT = RETURNED CONTAINING SUBSCRIPT OF RIGHTMOST
C LOCATION OF IBUFFR ARRAY INTO WHICH
C CHARACTER HAS BEEN PLACED BY THIS ROUTINE.
C IERR = -1 RETURNED IF REPRESENTATION OF ENTIRE
C INTEGER SEQUENCE WOULD NOT FIT INTO FIELD
C INDICATED BY LFTCOL AND BY EITHER IWIDTH OR
C MAXBFR, WHICHEVER INDICATES SMALLER FIELD.
C IF MAXBFR IS GREATER THAN OR EQUAL TO
C LFTCOL+IWIDTH, THEN IBUFFR(LFTCOL+1) THROUGH
C IBUFFR(LFTCOL+IWIDTH) ARE RETURNED
C CONTAINING ASTERISKS, AND KOUNT IS RETURNED
C SET EQUAL TO LFTCOL+IWIDTH. IF MAXBFR IS
C LESS THAN LFTCOL+IWIDTH, THEN THE ASTERISKS
C EXTEND THROUGH IBUFFR(MAXBFR) AND KOUNT IS
C RETURNED SET EQUAL TO MAXBFR.
C = 0 RETURNED IF ENTIRE INTEGER SEQUENCE COULD
C BE REPRESENTED IN FIELD.
