Program for diabetes

[CMarangon]

Hello!

I am trying to make a program for diabetes, for HP50.

In the program you enter one or several measuremens of glucose and store it in
a list, ∑dat.

So it calculates the media and the glycosylated hemoglobin, using the formula,
GH = 28,7 x A1C - 46.7.

Step 1:

Opening screen :
in the opening screen should appear:

"This program does not replace the medical appointment.
See your doctor regularly. "

I am open to new suggestions.

Can you help me giving your opinion?

Sincerely yours,

Carlos - diabetic, but fortunately my diabetes is under control
and I don't need to use insulin.
