HP50g help with numerical solver

[Aworx]

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.

Thanks

Try this link, to the HP museum, the link points to the forum, ask your question there, there are lots of HP50 dudes there. I use the trusty HP48G myself and they helped me out a bunch for a project of mine.
