HP50g help with numerical solver

  1. Jun 2, 2010 #1
    Hi, can anyone tell me how to add a text line in the numerical solver calculation screen that describes a variable in an equation?

    for example

    spl = 20 log (D2/Dr)

    Dr is a reference distance from a source
    D2 is a prediction distance

    I want some form of description of the variable when the cursor is moved to the input.

    So when I go to enter D2, the description appears on the bottom of the screen.
