CALL AXES(X0,Y0,ANGLE,V0,DV,DL,NMAJ,NMIN,NDEC,TITLE,NCHRS,SIZE [,JUST] ) --
 This routine will draw and annotate a linear axis.  FCTR: AX
 
 X0,Y0 - Location of the "origin".
 ANGLE - Angle in degrees of the axis wrt rightward going horizontal,
         positive being counterclockwise.
 V0 - Coordinate value at the "origin".
 DV - Change in coordinate value per major tick mark.
 DL - Length of major divisions, inches.
 NMAJ - Number of major divisions.
 NMIN - Number of minor divisions per major division.
 NDEC - Number of digits to the right of the decimal point.  If zero,
         no decimal point will be printed.
 TITLE - Character string containing title.
 NCHRS - In absolute value, the number of characters in TITLE.  If 
         positive, annotation is to left of the axis (typical Y); if
         negative, to the right (typical X).
 SIZE - Character size for annotation, title will be 1.5*SIZE.  If
        negative,  no annotation will be added.
 JUST - Optional argument specifying the justification of lines in
        TITLE represented by a single character; Default: 'C'.
 
 Note: An easy method of scaling and unscaling data is provided through
 the use of SUBROUTINE PSTN and NTSP.
