If you the menu and press NOTE on this particular aplet then you would see the attached Note shown right. This is quite common with downloaded aplets. Since they are non-standard, the author often ensures you have some instructions, although most of the documentation is generally in a Word® or PDF® document that comes with the aplet. This particular set of notes consists of a number of pages, but most aplet Notes are not that extensive. Indeed there may not be one if the operation of the aplet is fairly obvious. Most people don't read notes or explanations so it is debatable how much use they are anyway. Some aplets also have sketches attached to them but this consumes approximately 1Kb of memory per sketch and so was not common on earlier models which only had 23Kb of RAM memory and so didn't have a lot to spare. On the hp 39gs & hp 40gs, as programmers become used to having plenty of memory to use, aplets have become larger and more powerful. An example is shown above right of a sketch from one of the aplets available from HP's web site called 'Periodic'. If you installed this aplet on your calculator then this sketch could be viewed via the SKETCH key above the MATH key. Sketches can have multiple pages and are covered on page 222. 218
