Hello, the tutorials I found cover a small portion of the Scheme language. Often there's not even a conditional call (if) or loop like (while) explained (but they are nice introductions!). At http://www.swiss.ai.mit.edu/projects/scheme/documentation/scheme.html there's a reference manual, but I didn't manage to get some functions... to work. How about e.g. the (do) statement or (floor -4.3) (round -4.3) at scheme_5.html#SEC56 ..? It didn't work at the GIMP 1.2.3 script-fu console Is there a reference manual of the script-fu implemented Scheme? Thanks Martin -- ______________________________________ Martin Bernreuther MartinBern@xxxxxx
