Hi,

Given a string of type BABABBB and a pattern of AB, I would like to split the string into 3 sections: first=B, middle=ABAB, last=BB. I got the following pertinent code 

use strict;
my $string;
read(DATA,$string,7);
print "$string\n";

my $pattern = "AB";
print "pattern is $pattern\n";

my ($start,$middle,$end) = $string =~ /^(.*?)($pattern+)(.*?)$/g;
    
print "splitting\n";
print "start = $start\n";   #gets B
print "middle = $middle\n"; #gets AB
print "end = $end\n";       #gets ABBB


__DATA__
BABABBB

What is wrong with this regex? Please help. Thanks.
