You are sort of dreaming. There is a length function, and concatinating
strings is a built in feature (just plop the columns one after another
in the TEXT definition. The others would be easy to add if you want to
roll up your sleeves and edit mapparser.y.

Regardless, yes those that exist should be documented.

Hi all,

I seem to remember using some string function in the mapfile but I
can't find any reference to them. Do you know about them? can you add
them to the mapfile-reference.

http://mapserver.gis.umn.edu/doc40/mapfile-reference.html

It was used like:

TEXT (mid(3,-1,[FIELD]))
or maybe
TEXT (mid(3,len([FIELD]),[FIELD])

to generate extract characters 3..len([FIELD])

it seems to me that there were functions like:

mid(start,stop,string)
left(num,string)
right(num,string)
len(string)
concat(string1,string2,...)

Have these gone away, was I dreaming, or replaced by regular
expressions? If these are still valid, they should get added to the
Mapfile reference.
