      SUBROUTINE GRSLW (IW)
      INTEGER IW

 GRPCKG: Set the line width for subsequent plotting on the current
 device. If the hardware does not support thick lines, they are
 simulated by tracing each line with multiple strokes offset in the
 direction perpendicular to the line. The line width is specified by
 the number of strokes to be used, which must be in the range 1-201.
 The actual line width obtained depends on the device resolution.
 If the hardware does support thick lines, the width of the line
 is approximately 0.005 inches times the value of argument IW.

 Argument:

 IW (integer, input): the number of strokes to be used for subsequent
       plotting on the current device (in range 1-201).
