lsback(3G)

NAME
     lsback - controls whether the ends of a line segment are colored

FORTRAN 77 SPECIFICATION
     subroutine lsback(b)
     logical b

PARAMETERS
     b   expects either .TRUE. or .FALSE..

         .TRUE. forces the last pixel of a line segment to be colored.

         .FALSE. allows the linestyle to depend whether the last pixel of a
         line segment to be colored.

DESCRIPTION
     lsback enables or disables linestyle backup mode.  This mode controls how
     the final pixel of a line segment are rendered.  If it is enabled, it
     causes the current linestyle to be overridden and forces the final pixel
     of a line segment to be colored. If it is disabled (the default), this
     does not happen, and line segments can have invisible endpoints.

NOTE
     This routine only functions on IRIS-4D B and G models, and therefore we
     advise against its use in new development.
