I once got the same problem when "inventing" InstallKit. If you attach data
at the end of a bounded file, the last line of your program should be
"abort(0) [ENTER]". If you don't do this the Euphoria interpreter just tries
to go on reading the source file... and voila! you got an error. If you use
a comment mark ("--"), it work for a certain amout of data. If the data is
too long the interpreter complains "line too long" or something like that.
