GIS Students:

There is an option for using INFO lookup tables for both symbols (shades, 
etc.) on the map and as a keyfile.  When you create your lookup table, 
add a third item (after the code item and SYMBOL) called DESCRIPTION.  
Define DESCRIPTION as a C type item, long enough to include the text you 
want to display for a given class in the legend.  Then add symbols and 
legend text in info.

What if you already have a lookup table?  I'll let you figure that out -- 
you *ought* to know.

As a lookup table for say polygonshades, the usage is no different -- the 
SYMBOL item is used.

To use this option for key legends (e.g. KEYLINE, KEYSHADE), the usage is 
something like:

Arcplot: KEYLINE ROADS.LUT INFO SYMBOL DESCRIPTION

Thus you've told it the name of the file (this time not a text file but 
an info file of course), that you want to use the INFO option, and to 
read the symbol (in this case line symbol) from the item SYMBOL and the 
legend text from the item DESCRIPTION.

KEYSHADE works the same way.

Ok?

Ok.
