Yes exactly - I do not know how this would turn out in Gimp-Scheme (and especially of course in versions to come): (define blur-file "blur.png") (define blur-file "otherblur.png") Different versions of Scheme handle this differently. I do not know if this is proper Gimp-scheme (re-defining a defined variable), or if one would have to use set! for the second definition/assignment. Incidently, no script-fu seems to make use of global variables, only of local let* - environments. Perhaps (define ...) is equivalent to (set! ...) here? Markus.
