[Richard Greenwood]

I have pasted a simple thematic layer definition below. You define the 
colors or patterns for the thematic map in the MAP file. The "Zoning" field 
in my table has a two character field that I want to thematically map (the 
CLASSITEM). Then I define a class for each zone. The important thing in 
each class is the EXPRESSION. You only need to give a class a NAME if you 
want it to have a legend.
