Programming Help

[ArmoredCow]

I'm trying to write a program to help with some Kinematics equations. However I'm new to HP PPL and could use some advice and help on where to get started.

I would like to have it look something like the triangle solver app but when I tried to modify that app I can't get at the code and it just comes off as a clone of the triangle app.

I have some basic code that allows for input of the variables but I'm not sure how to set up a button to start solving for the missing information. Also it would be helpful if I could have the variables set to null so I can tell which ones the user has set and not have them all default to 0.

The very limited code I have is below...

Code:


// Starter Program to help solve Kinematics problems

EXPORT Kinematics()
BEGIN
    INPUT(
    {
    {Vi, [0], {15, 30, 0}},
    {Vf, [0], {65, 30, 0}},
    {Ti, [0], {15, 30, 1}},
    {Tf, [0], {65, 30, 1}},
    {Si, [0], {15, 30, 2}},
    {Sf, [0], {65, 30, 2}},
    {A,  [0], {15, 30, 3}}
    },
    "Kinematics Solver",
    {
    "Vi=", "Vf=",
    "Ti=", "Tf=",
    "Si=", "Sf=",
    " A="
    },
    {
    "Velocity Initial",
    "Velocity Final",
    "Time Initial",
    "Time Final",
    "Position Initial",
    "Position Final",
    "Acceleration"
    },
    {10,20,30,40,50,60,70}
  );
END;
