PUZZLE is a version of the 15 squares sliding puzzle for the Psion 3a. Not a very original idea, but a fun project to learn programming on the 3a. It is freeware, I hope you enjoy it. To install: copy PUZZLE.OPA to the APP directory on any drive and use the install command in the system menus. I have included the source code PUZZLE.OPL and the icon PUZZLE.PIC in case anyone is interested. Mark E. Reid Charleston, WV
