# hidsflt1.qry
# This is a sample script for drawing a high-angle dip-slip fault
# line (solid) with U and D marking upthrown / downthrown sides of
# the fault.  The U symbol is drawn on the left side of the line.
# If this is the wrong side for an individual line, use
# the Spatial Data Editor to reverse its start and end points.
# Modified for legend samples August 2002.
# Modified to declare all variables, October 2005
# Version Dec. 2007
# Requires TNTmips 2007:73 or later.
# Modified to adjust scale based on georeference map units and to
# put offset symbols only at the center of each line
