If we're diligent, we can complete the Nspire command pages.

In the double window of the Calculus mode of my calculator, programs can't be called when I call them. I require the program to Display something and when I call it nothing happens.

I upgraded to OS 4.5.5 before realizing it wasn't supported by Ndless. So now I want to remove the os protection or flash it to downgrade the os and install Ndless. I'm willing to buy the USB/TTL interface. Thank you!

Trying to convert TI-83 code for Slope Field into TI-nspire CX (not CAS)

Is it possible to open dialogs with more than one input?

How to select parameters.

Looking at creating Erlang Distribution Program

Looking for help constructing some differential programs

I want to convert real number to integer: like 1. to 1

When I run the code below, it works fine. (TI nspire CAS II calculator) However at the end of the program I give two options, "Enter" to repeat the program, "Esc" to quit. "Esc" works fine. However if I pick "Enter", the RequestStr box pops up again to receive the new input as intended. When I enter the input, the program displays "You entered nothing" and goes back to the RequestStr box again. I have to press "Cancel" on the RequestStr box to get out of the loop. "You entered nothing" is part of the error code I am using to intercept the case where the user may click OK without entering anything into the box. So basically the program works fine the first time I run it, it is when I choose to rerun it again is when the issue arises. Any help will be greatly appreciated. T Gahan
