You can also use this bizarre construction to capture just the count:
$_ = ABabcde12345BAABabcde1234blahblah5BA;
$count = () = $_=~ /(AB.*?BA)/g;
print I matched $count times\n'
the () between the two ='s forces the match to list context, and then
THAT is forced to scalar context by
If you're using ActiveState Perl, an easy was is to use the wperl
executable instead of the perl executable to run your scripts.
Scripts you want to run w/o the dos box could have a .wpl extension
instead of .pl, and you could associate .wpl with wperl.

There's a fun little idiom using tr/// to count the number of
occurances of a character in a string:
perl -le '$str = a,b,c,d,e; $count = ($str =~ tr/,/,/); print $count'
will output 4, the number of commas in a,b,c,d,e.
