Expression help

[Fawcett, David]

The easiest way would be to pre-class them (1 - 8) in ArcView, Access, or some other database program.

I can't help you with the regular expressions, but if you search the archives at 

http://mapserver.gis.umn.edu/cgi-bin/wilma/mapserver-users

you should be able to find some examples.

> I'm needing help writing expressions to classify forest stands by age.  My shapefile includes a data item named "AGE2000" which is a numeric item representing the age fo the stand.  How do I need to set up classes if I want to represent the data in 10-year age classes.  Values of "AGE2000" range from 0 to 74.  Right now I have:
> 
> LAYER
>   NAME standage
>   TYPE polygon
>   STATUS off
>   DATA stand110
>   CLASSITEM "AGE2000"
>   CLASS
>     NAME "0 - 9"
>     EXPRESSION "???"
>     SYMBOL 0
>     OUTLINECOLOR 0
>     COLOR 50 255 50
>   END
>   CLASS
>     NAME "10 - 19"
>     EXPRESSION "???"
