Hi Bruce,

in general integer operations are fastest for the native word size, meaning 8-bit or 16-bit operations are not faster than 32-bit operations on modern CPUs.

This tells us byte and short mainly exist to support compatibility with existing data structures, files, etc; and of course to economize on memory when using large amounts of them as in arrays.

BTW: This may not be very easy to test, since (1) programming languages use the native size for literal values anyway, and (2) often the compiler will use int operations although byte or short where coded when those ints are equivalent to what you actually coded.

Smile | :)
