Crap. An integer is any whole number. fractional values eg 1/2, 1/4,
567/24 etc are not integers, but they are numbers.

What on earth are you talking about? line 5 defines $key, line 13 uses
$keys, 2 totally different variables.

Richard, stop trying to debug people's code, you really have no idea what
you're talking about most of the time .... which I guess is nothing new.
