Heh, ASCII means plain text.
It looks like you'd do something like this (haven't tryed any of this out yet)
openFileInput("info.txt","Files") // 'Files' is the folder you put the file in, e.g. 'Prg'
dest$ = fileInput("info.txt") // dest$ will be the info is stored in
...
closefile("info.txt")
fileInput() reads one line from the file, and each call will read the next line until it gets to the end.
