    Variant: 16 bytes for any datatype except strings, which need 22 bytes + stringlength * 2
    Boolean: 2 bytes
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    Isn't a boolean only 1 byte? I mean, what's the difference between an integer (2 bytes) and a boolean, if it's also 2 bytes.
    I know in VB3, the boolean data type did not exist, so I presume that this type only uses 1 byte.
    I'm not sure. Please correct me if necessary...

    A boolean consumes 2 bytes, i know it sounds stupid but that's what it does, it's like enumerations, they are integers to allow negative numbers and -1 is true for a boolean variable, dunno if that's the connection..

    So, for using one byte, do I need to declare String * 1 as data type?

    byte datatype eats one byte and represents a numeric value from 0 to 255, if thats what you need. String*1 would consume 2 bytes and is represented as a string
