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 - HP 39GS | hp 39gs_user's guide_English_E_HDPMG39AE13.pdf - Page 232
run the menu configuration program to configure the aplet's VIEWS menu. 6. Test the customized aplet and debug the associated programs. (Refer to "Debug a program" on page 16-7). Aplet naming convention To assist users in keeping track of aplets and associated programs, use the following naming - HP 39GS | hp 39gs_user's guide_English_E_HDPMG39AE13.pdf - Page 233

For example, these can - HP 39GS | hp 39gs_user's guide_English_E_HDPMG39AE13.pdf - Page 237
, or you want to transfer a sub-program that other menu programs use. Auto-run programs If the Prompt item is "Start", then the ProgramName program runs whenever you start the aplet. This is useful for setting up a program to configure the aplet. Users can select the Start item from the VIEWS menu - HP 39GS | hp 39gs_user's guide_English_E_HDPMG39AE13.pdf - Page 238
the associated program finishes, you would specify 1 as the ViewNumber value.
