Query expression and result

[Stephen Lime]

Its a symbol set issue. I imagine the demo you downloaded was pre-3.3 and
has old symbol sets. Replace the file 'line.sym' in the ms_demo/symbols directory
with the one attached and give it another try.

On the expression front again the 3.2 demo is wrong. ^- is a regular expression
that means anything starting with a minus sign. Regular expressions should be
enclosed in //'s so change the occurances of "^-" to /^-/. Other expressions
are tests for equality and should be fine as is.

A new 3.3 only demo is underway. Yes, a book would be nice. Any co-authors?
How bout a user group meeting?

Thanks to some helps from the members in this list, I am able to load
graphic and data from mapserv.  The only problem is when I click on the map,
the result comes back as :  "getNumeric(): Incorrect data type"  ...what
does this mean?
Also, in a query syntax, what does the "^-" indicate? i.e., EXPRESSION "^-"
Maybe a book about mapserver is needed :-)   
Thanks,
