Use of % in a varible name

[Steve Lime]

Yes, you can do numerical comparisons. Remember the %foo% indicates a
run-time
substitution and is not actually present when the expression is
processed. A % in
an expression post substitution is a modulus operator that does require
numbers on
each side.

Did the following not work?

  EXPRESSION (%foo% gt 5000)

Hi Folks

I know its possible to use the string syntax  '%foo%'  where is foo is

an input value from a httml <input type="hidden" name="foo"
value="haggis"

is it possible to use a numerical value with the same syntax ?

eg

                   %foo% lt 50000

where


<input type="hidden" name="foo" value="5000"

Line 326 of mapparser.y( map server 4.10) seems to indicate for 
numerical expressions a % is always used as an operator

I am trying to pass a varible in to a cgi version of mapscript and do a

numerical comparsion

 From the documntation it appears that saying

    expression "[foo]" gt "5000" will not work as expected, is this 
correct ?/

Dave.
