C ************************DEFINE PLOT FORMAT************************
C
C VARIABLES LTTRS, LINES, IDIVX, IDIVY, ICHAR CONTROL PLOT FORMAT.
C THESE CAN BE MODIFIED IF DIMENSIONS ARE INCREASED WHEN NECESSARY.
C MINIMUM NUMBER ARRAY DIMENSION IS = LINES*((LTTRS+IBITS-1)/IBITS).
C MINIMUM LIST ARRAY DIMENSION IS = 8*((ICHAR-6)/IBITS).
C MINIMUM IBCD DIMENSION = ONE PLUS WIDTH OF PLOT IN PAGES.
C DO LOOPS REQUIRE CHANGE IF COUNT OF BITS USED PER WORD IS CHANGED.
C
C LTTRS = MINIMUM COUNT OF CHARACTERS TO BE PRINTED ACROSS PLOT
C
C LINES = COUNT OF LINES CORRESPONDING TO HEIGHT OF PLOT
C
C IDIVX = COUNT OF LINES WHICH CORRESPONDS TO A PLOT HEIGHT OF ONE
C
C IDIVY = COUNT OF LETTERS IN LINE WHICH CORRESPONDS TO WIDTH OF ONE
C
C ICHAR = MAXIMUM NUMBER OF CHARACTERS TO BE TYPED ACROSS PAGE WIDTH
C
C NTAPE = TAPE UNIT ON WHICH THE PLOTS ARE TO BE PRINTED AS OUTPUT
C
C IBITS = COUNT OF BITS USED PER WORD OF NUMBER STORAGE ARRAY.
C
C THIS SUBROUTINE IS PRESENTLY SET UP TO STORE PLOTS AS 216 LINES
C (LINES=216) EACH CONTAINING 360 CHARACTERS (LTTRS=360).
C FOR PRINTING, THE PLOT WILL BE BROKEN INTO 3 PANELS 1 PAGE WIDE
C BY 216 LINES LONG SINCE UP TO 132 CHARACTERS (ICHAR=132) CAN BE
C PRINTED ACROSS THE WIDTH OF A SINGLE PAGE.
C LEFT AND RIGHT MARGINS ARE 10 CHARACTERS WIDE ((LTTRS-IDIVY)/2=10)
C UPPER AND LOWER MARGINS ARE 6 LINES WIDE ((LINES-IDIVX)/2=6).
C POINTS OR LINES OUTSIDE THESE ERROR MARGINS WILL NOT BE SHOWN.
