There is no problem to use the equivalent decimal numbers for programming.

Good Day:
Does anyone know if the Solutions Cubed Pocket Watch B
needs to be programed in Hex? Their programing
examples show Hex being used which is a lot harder for
me......

What would be the advantage of Hex?

Thanks,
Andy Shor

    Two thoughts regarding Hex.

    Bytes represented in Hex are frequently written using two characters, even
    when the leading digit is a 0. This makes multiple lines of hex values
    easier to read since every value is always two ASCII digits, and therefore
    the values line up better than decimal (values having anywhere from 1 to 3
    digits).

    Since much of what we do with microcontrollers is bit-oriented, knowing a
    number's binary representation is frequently useful. Once you get used to
    working with it, looking at Hex, it's easier to visualize the binary
    equivalent of the value than decimal.

    Thanks for your time and the info. I'm much relieved!

    Good Day:
    I guess another advantage is Hex takes up less space
    in the larger numbers?

    I expect not. Usually they're both reduced into binary form ; I expect the
    pbasic interpreter treats 127 and %01111111 the same way.

    I think what he meant was the ASCII representation of the number in decimal
    format could be three digits, vs. the hex representation always being two.
