Regardless of what the situation was in Pascal's time, they are currently integers. The order of bytes in the array would need to be adjusted depending on the machine endianness to be correct. The C argument passing convention is different for byte arrays than for integers (presumably the most common use of these constants is to use them with Apple libraries). Different constants within the same enumeration are sometimes specified as decimal integers, and sometimes as character constants. For example, the QTNewGWorldFromPtr function uses an enumeration which includes k32BGRAPixelFormat, defined as 'BGRA', and k32ARGBPixelFormat, defined as 0x20. Providing a convenience str() method may be handy, but the internal representation must be integer.
