Parser and question

Hawke,

        Just wanted to say THANKS for EUServer, I was working
on a Parser for an Text Adventure Game, I had worked a long time
on this parser, but the code was getting KLUDGED.  I took the
approach used with EUserver's cmdlist.ew & basiccmd.ew, loved the
approach here.  I was able to Re-Write the Parser to some extent
in very little time, and adding additional commands is a breeze.
So, that was a long way to go to say Thanks and keep up the good
work.

A question for ALL,

        This is probably a question that has been asked millions of
times, and if so Sorry for asking again, and it may cause my DUH side
to show a little, but the problem I seem to be having is figuring out
HOW to convert a sequence to an integer?  Example.

global integer Score
        Score = 0
    .
    .
    .
procedure AddToScore(sequence Amt)
        Score = Score + Amt
end procedure
    .
    .
    .

Person inputs a command > addtoscore 10

program uses Ch = gets(0)

program tries to do AddToScore(Ch[2])

what happens here is obvious Euphoria returns an type check failure
of course, this makes since since you are trying to add something
non numeric to a numeric variable so to speak.
