Use the SETVIEWS command to create a custom VIEWS menu which links specially written programs to the new aplet. A useful method for customizing an aplet is illustrated below: 1. Decide on the built-in aplet that you want to customize. For example you could customize the Function aplet or the Statistics aplet. The customized aplet inherits all the properties of the built-in aplet. Save the customized aplet with a unique name. 2. Customize the new aplet if you need to, for example by presetting axes or angle measures. 3. Develop the programs to work with your customized aplet. When you develop the aplet's programs, use the standard aplet naming convention. This allows you to keep track of the programs in the Program catalog that belong to each aplet. See "Aplet naming convention" on page 21-10. Programming 21-9
