Is set!/define the only difference with the new script > engine? I edited a few more and all seems well. > I am not sure, I am just learning. The main difference is the interpreter Tinyscheme vs SIOD, each one has its own interpretation of the standard. About set!, it serves to put a value to a variable, not to declare it. Say open a gimp script-fu console and type the following: (set! x 1) ---> Error: set!: unbound variable: x (define x) ---> x (set! x 1) ---> 1 As you see, set! works once the variable is declared.
