Just a bit of (probably excessive) detail...
In order to get the WORD_LENGTH letters as letters, OR to prompt if I didn't get them, I needed:
while (length($target_letters) != WORD_LENGTH ||
$target_letters !~ /[^A-Za-z]/) {
# prompt
}
process the word
That is, I changed the && to || and reversed the match to !~, now it works like a bought one.
Thanks chipmunk for your suggestions... I'm a bit
of a newbie, and will need to read up on the syntax there.
I know (a little) about array and hash references, including (even littler) about anonymous ones but I'd been `saving' myself from subroutine refs, as they make my head hurt a bit at this stage of my vocation 8-)
