"THIS program uses screens saved on tape or disc to form a simple puzzle. If you haven't got any saved screens, it will create one out of random lines - just press Enter / Return when asked for a filename.
The picture will be divided into 16 tiles which are then shuffled around. You have to reassemble the picture by swapping pairs of tiles - specify two numbers separated by a comma where 1 is the top left hand tile and 16 is the bottom right."
