Custom Menue in RPN mode

[Jacob Wall]

A true custom menu is not possible on HP Prime. Any custom menu implementation will have to be within the context of another application or program. One example is something I created RPN Prime SurveyCalc which has various menus that can be accessed while using the app.

It would be possible (if one was motivated enough) to create an app (just a PPL app even) that would essentially replace the RPN mode of the HP Prime which included an implemantion of a custom menu feature. The app I created was to address the needs of a small segment of the larger possible user base, and it was enough for me to be able to switch from using a 50g daily to using the HP Prime daily. To add a custom menu in that app would likely be done via an interface allowing the user to select from a predefined list of functions to populate a certain menu, or to enter a custom name. With a bit of creativity the "Programs" variable could be used to check whether a custom name matched a user program name, but a whole lot of complexity would arise from that of course. Within the scope of an RPN stack, there would need to be some checks as to number and type of arguments, etc. All possible still, I lack the time to go down that path and frankly I'm not convinced Moravia is "all-in" on the HP Prime anyways, meaning that any effort would face the uncertainty of being built for a product that faces an uncertain future.
