Thanks to Michael Long’s Menus for HyperCard stack, Doug Werner’s HyperEdit stack, and Andrew Gilmartin’s FileName stack for the scripts in them that use ResCopy. Thanks to Lloyd Maxfield’s BarButton stack for giving me the idea of including the source code for this XCMD in the stack. Thanks to Andrew Gilmartin for his FileName XFCN and to Steve Maller for his ResCopy XCMD, which are both present in this stack. Also thanks to Eric Alderman for a tip regarding horizontal scroll bars in hypercard, which appeared in his column in MacWeek, that made rethink the usefulness of ScrollingCards and develop it into ScrollControl. Finally, special thanks to Lloyd Maxfield for making the source code of his BarButton stack available, as a portion of the code for ScrollControl comes from his code. My own Alert XCMD is also in this stack.
