      SUBROUTINE GRSLS (IS)
      INTEGER IS

 GRPCKG: Set the line style for subsequent plotting on the current
 device. The different line styles are generated in hardware on
 some devices and by GRPCKG software for the other devices. Five
 different line styles are available, with the following codes:
 1 (full line), 2 (dashed), 3 (dot-dash-dot-dash), 4 (dotted),
 5 (dash-dot-dot-dot). The default is 1 (normal full line). Line
 style is ignored when drawing characters, which are always drawn with
 a full line.

 Argument:

 IS (input, integer): the line-style code for subsequent plotting on
       the current device (in range 1-5).
