Hi, this is probably a noob question, but I have found good help and activity here so I hope I can get help with this other issue with a board game me and my friend is programming :) The program consist of an instance (current-game) of our class game% and a GUI (frame%). And we want to add a save option to the menu. ;This is almost the first line of code in the program (define current-game (new game&)) Can we print current-game to a file with a command such as: (define out (open-output-file "save001.sav")) (write current-game out) (close-output-port out) and load it with (define in (open-input-file "save001.sav")) (set! current-game (read-line in)) (close-input-port in) Is it possible to do something similar in a method to the game% class (refer to the instance itself)? Or do we have to store all members of the game% instance one by one? Will the loading get screwed up with we change a minor thing in the game%-class? // David (does anyone want to take a look on our code? This is our first (graphical!) game and we would love all the help we can get. :))
