BYTE Function: Windows

If the BYTE function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 1.

Because Windows is an ASCII system, the BYTE function returns the nth character in the ASCII collating sequence. The value of n can range from 0 to 255.

Any programs using the BYTE function with characters above ASCII 127 (the hexadecimal notation is '7F'x) can return a different value when used on a PC from another country as characters above ASCII 127 are national characters and they vary from country to country.
