Shore - 01-21-2022 03:27 PM Steps: 1. Create a new program. Press [ Shift ], [ Esc ] (Clear) to clear the default text. 2. Press [ Menu ] and select 4. Create User Key. Press a key combination. 3. Use a CHOOSE command to create a pop up menu. Enclose commands in a string. For mathematical expressions, use parenthesis. You may need to test commands. 4. Use the RETURN command to return a user's choice. To use the custom menu: Press [ Shift ], [ Help ] (User), < your user key> Template: KEY K_() BEGIN ... CHOOSE(var, "Custom Menu", list of commands) RETURN list(var); END; The following is an example menu with the following commands: 1. DDAYS - days between dates (yyyy.mmdd) 2. DATEADD - add number of days to a base date 3. QPI - find an exact representation of a floating number 4. approx - approximate an exact number 5. B→R - base number to real number 6. R→B - real number to base number 7. *(π/180) - convert from degrees to radians 8. *(180/π) - convert from radians to degrees 9. rectangular_coordinates - convert polar coordinates to rectangular coordinates (Geometry app). Use a vector or a complex number. A. polar_coordinates - convert rectangular coordinates to polar coordinates (Geometry app). Use a vector a complex number. The angle symbol is found by [ Shift ], [ × ] HP Prime PPL Program: CUSTOMMENU I use the Toolbox key. Code: ```KEY K_Math() BEGIN LOCAL LM, I; LM:={"DDAYS()","DATEADD()", "QPI()","approx()","B→R()","R→B()", "*(π/180)","*(180/π)", "rectangular_coordinates()", "polar_coordinates()"}; CHOOSE(I,"Custom Menu",LM); RETURN LM(I); END;```
