pbasic 2.5 question.

Hello all,

I'm learning PBASIC 2.5 from a book called PROGRAMMING AND CUSTOMIZING THE BASIC STAMP COMPUTER and I ran into this situation. The following code produces the output under it:

code---------------------------------------- ' {$STAMP BS2} ' {$PBASIC 2.5}

_x VAR Byte _y VAR Byte _z VAR Byte _area VAR Word _x = 20 _y = 30

B0 = 155 B1 = 220 W2 = B0 + B1

_area = _x*_y 'solve the area

DEBUG "the Area is ", DEC _area, "sq ft." DEBUG CR, ? B0, ? B1, ? B2, ? W2 END ====================================== OUTPUT: the Area is 600sq ft. B0 = 88 B1 = 2 B2 = 20 W2 = 375 =====================================

My questions are:

-why is B1 = 2 when I declared it '220'?

-why is B2 = 20 when I didn't load it with any values?

-W2 is giving me the correct sum, but why are the B variables displaying strange results?

How many sensors are used in your robot?

Thanks Nick

Alex, I'm not an expert but it looks like B0-B13 are registers (hard wired memory locations in the microcontroller). While the program runs the contents are constantly changing. Dana
