I've read perlre and perlop, and I've read the Q&A on regexes, but there's something that I think I'm missing. If I want to find
$x = 'ABCD',
but I don't care if it's interrupted by anything non-uppercase, how do I specify that?

For instance, I want this to match:
$string1 = 'ABhere is intervening textC D',
and so would this:
$string2 = 'A B C, lots of text and numbers and equals and slashes DEFG'
but this would not:
$string3 = 'ABhere IS intervening TEXTC D''

I am guessing that simply specifying =~ /[A-Z]$x/gx wouldn't do it. That would just specify that the match had to be uppercase, which is redundant, given the string definition and lack of a /i, right?

If anyone could please just point me to what I might have missed, or offer advice, I'd really appreciate it.

Thanks
Matt
