[plt-scheme] unexpected things in .ss files

You can use the "save as text" menu in drscheme, or you can write a
program that does this conversion manually. Here it is:

(define (convert in-filename out-filename)
  (let ([t (new text%)])
    (send t load-file in-filename)
    (send t save-file out-filename 'text)))

Alternatively, you can process the program directly as a text% object,
without losing information (saving as text loses information,
potentially. Images becomes dots, etc).


PS: did you see what happened when you right-clicked on either the
fraction or the number?
