PPL INPUT function

[jlastofka]

I'M having a lot of trouble with the INPUT function. It seems very buggy, working differently on various runs of a simple program. I've got the latest Firmware (flashed it twice), and I've reset the calculator with the pin hole, and Apps Esc On, and the FCO method. I've deleted all the programs and reset the user variables. And I've tried other programs similar to this with the same result.

Program calculates Euler buckling of beams:

EXPORT BUCKLE()
BEGIN
K:=1;
INPUT(E);
INPUT(I);
INPUT(L);
F:=E*I*pi^2/(K*L)^2;
RETURN F;
END;

( pi IS REALLY THE GREEK SYMBOL
AND THE ^2 ARE REALLY SUPERSCRIPTS,
I JUST DON'T KNOW HOW TO PUT THEM HERE)

This will work a few times. Then it will start corrupting the E,I and L variables and causing run errors or bad results. I'll do some editing and it will work a few times and then start corrupting again. I've also tried the longer INPUT(E, "text", "text", "text", 100); optional version. It ignores the 100 value and pretty much misbehaves like the simper version. All else on the calculator seems to work well.

If I take out the INPUT lines and use EXPORT BUCKLE(E, I, L) to get the I/O it works fine, but then of course I have to type in all three values every time I rerun the program. And I want my INPUT function to work right anyway.

-AND- I get the same bogus behavior on the PC emulator, too. I guess I'm doing something wrong, but I don't see it.

Thanks for any help.
