GW-BASIC sytle label names are an anti-pattern. It's better to name the
labels after what they do, just like function names describes what the
function does. Here it would be "goto clear_desc;" or something. It
doesn't have to be perfect but so long as you *try* to name it something
useful that's better than not trying.
