      SUBROUTINE ISLWSC(WIDTH)
*.===========>
*.
*.   Purpose:
*.   --------
*.     Set the linewidth primitive attribute.
*.
*.   DI-3000 access:
*.   ---------------
*.     CALL JLWIDE (CVALUE)
*.
*.   Parameters:
*.   -----------
*.     CVALUE                     [ INTEGER; Input ]
*.
*.      - The new value for the linewidth.
*.
*.        *NOTE* : CVALUE must be in the range 0...32767.
*.      Default linewidth = 16383 (midrange)
