I've managed to make my old script working. The problem I got was a misunderstanding of scheme syntaxes as it wasn't expressively shown. I saw examples like (let ((x 1) (y 2) (z 3)) (list x y z)) at http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme-Z-H-7.html#node_chap_5 So I thought the first parenthesis after let had intension to enclose _several_ assignments in one let operator. All the samples there had the structure with more than one assignment, so I tried: (let (x 1) ... ) and it didn't work. After some thoughts I understood that one pare of parenthesis is used all the time to enclose the assignment part of the let operator regardless to the number of assignments. So, maybe it is too lame, but If I saw in the transition guide something like this: (let ((x 1)) (set! x (+ x 4)) ) and (let ((x 1) (y 2)) (set! x (+ x y)) ) it would save me a lot of time. -- With respect Alexander Rabtchevich _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
