I just bought a WP 34s and I have been trying to figure out how to use it.

I made the following program (the calculator is in radians):

step 001: LBL A

step 002: COS

step 003: RTN

setp 004: END

I then exit

I then push 0 press enter

Push 10

push integration button (g-function 2)

push A

I see numbers close to the answer cycle on the screen

then the screen turns off

I turn the calculator back on go to program steps (h-func R/S) and I see a bunch of random ERROR codes like 0363 (didn't scroll through them all but it goes down to error 324 and less)

I have firmware version: 34s3.3T3887 (HP 30s)

I tried the same sequence of steps on the newest emulator and it works fine.

Is this calculator I just spent 180CAD$ on junk? or did I do something wrong?

(I tried pressing the reset button on the back of the calculator)

(NOTE: taking the integral of y=x seems to work most of the time)

(JUST TO BE CLEAR: I see the correct (or close to correct answer) on the scree of =~ -0.54, then the screen turns off I power the calculator back on and see the wrong answer: -0.60120 in the x-registry)
