Paul,


Maybe you have a hard return at the end of the file?  That would append

chr(13) and chr(10) -- carriage return and linefeed -- to the string

you're reading in.  You could use a substring function to get rid of

those "characters."  One quirk of Flash is that if you read in text with

hard returns in it and display it in a textfield, Flash outputs a new

line for *both* the carriage return and the linefeed characters, so you

end up with double spacing when you don't want it.  For a routine to get

around that, search on "double returns" at
