PURPOSE:
========
This AML draws a USGS-type barscale at any scale while in an ArcPlot 
map composition.

USAGE:
======
&r barscale {x} {y} {custom}

Use an x,y coordinate pair, or enter "#"s to locate the barscale with the mouse.
If no arguments are given, the mouse will be used for location.  The location
point is the center of the topmost scale bar.

Anything entered for the {custom} argument, other than no, NO, N or n, will be 
interpreted as a custom option. For the custom option the user will be prompted
to enter the # of divisions, the interval, and the # of subdivisions for each 
unit (meters, miles and feet). The subdivisions are the smaller intervals on 
the left part of the scale. You may also select the top-to-bottom order of the
individual scale bars. If doing a 'standard' USGS scale (12000, 24000, 25000,
50000, 62500, 63360, 100000), the intervals and divisions are preset unless you
specify that you wish to exercise the custom option. Read the notes portion of
the AML header.
