Is there any reason not to use these binary constants instead of hexadecimal constants in the real program?

Absolutely not! I actually had to write the binary down and convert to derive the hex.

Why did I do that? Simply, because I forgot that Perl can handle binary constants. Dumb, but true.

I especially like your use of the benign underscore to clarify the breakdown++

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
