Cannot delete file Message #1 Posted by Les Koller on 6 Nov 2013, 12:48 a.m. Wen I press the PROGRAMS key, I have a file I did not put there, called FUNCTION(APP). I believe it is a consequence of playing with the Quadratic Explorer App. It has the basic template of a program, and I can edit it and such, but I cannot delete it to save me. I have tried every reset trick to go back to factory settings. How do I make it go away? <edit> I finally got the reset to work, even reformatted the flash. It deleted everything off my Prime EXCEPT the offending FUNCTION(APP) file. Edited: 6 Nov 2013, 12:58 a.m.

Re: Cannot delete file Message #2 Posted by Michael de Estrada on 6 Nov 2013, 1:13 a.m., in response to message #1 by Les Koller It will always be the last App you opened, so if you open another App such as the Spreadsheet or whatever, then that will appear in the program list in its place. It is NOT a bug. It allows you to create or edit a program that appears in the App screen and is actually a pretty neat feature.

Re: Cannot delete file Message #3 Posted by Geoff Quickfall on 6 Nov 2013, 1:15 a.m., in response to message #1 by Les Koller Function App is part of the built in OS just as Finance, Geometry and etc. Select another app, say geometry. Then go to the Program library and you will see the new app listed at the top of the screen above your other programs. You cannot remove the new app listed at the top of the program screen. It will always reflect the last selected app from the app screen. Unless I am missing something in your question. Geoff Michael and I were typing at the same time, he beat me to the post button :-0 Edited: 6 Nov 2013, 1:16 a.m.

Re: Cannot delete file Message #4 Posted by Marcus von Cube, Germany on 6 Nov 2013, 2:17 p.m., in response to message #1 by Les Koller As Michael and Geoff have already stated, the program is tied to the application just started. It can be modified to change the behavior of the application (redefine views and such). This makes most sense if you SAVE the application under a different name (which will create a shallow copy of the app). This is the way custom applications can be created on the device. What's missing is an SDK to create an application from scratch. On the predecessors of the Prime and the 39gs II, namely the 38G and 39G (and the siblings 39gs, 40G and 40gs), you could do it in SysRPL. On the Prime this will most probably be C++. The ancient ADK for the 38/39 series can be compared to the Connectivity Kit of the Prime: Apps created with this tool on the PC use only user level programming.
