Convert number to letter

Question

Hi there
I am trying to find a way to convert a number to a character
for a game I am working on. Currently the users score can be sent
to a friend via a query string e.g.
www.mygame.com/game?usersscore=111.11
This is not ideal as all the user needs to do is alter the
query string to automaitcally change their score. So what I want to
do is disguise the score as a series of random letters. e.g. 123.12
= abc.ab
Then when the flash reads in the query string abc.ab it
converts it back to the score of 123.12
I have looked at converting the score to hexidecimal to
disguise it but can you convert a decimal number with a point in it
e.g.22.5 or would it only except whole numbers?
Any help on this would be much appreciated

my game it doesn't seem to work properly. Basically my send to a
friend section appears on the last frame of the game. At this point
i give the user the url using the encode function.
I have added your code and have got the game encoding the the
score to the letters (Great so far)
However if you are starting a game the decode function needs
to be on the first frame of the flash movie to show the user their
friends score (e.g. so it can work out that bbcc is 1122 for
example) based on the query string. However the decode function is
never passed the encode result as the flash movie doesn't get to
the last frame:
decode(coded); //send to decode the test string
So I need to be able to encode on the last frame (which is
done) and then decode on the first frame.
I tried this but its not outputting anything:
varchallengerscore = "ab"; //I am trying to pass the value of
this variable to the decode function
decode(varchallengerscore)
function decode(str) {
var decoded:String='';
for(var i=0; i<str.length; i++) {
if(i==str.length-2) {
decoded+='.';
for(var j=0; j<char.length; j++) {
if(char[j]==str.charAt(i)) {
decoded+=j;
break;
trace(decoded); //test output
any ideas? Also I hope this all makes sense to you and I am
describing the situation ok. So far you guys have been a massive
help so thanks.
