I have a text file that contains many sections. I want to extract certain sections with associated content. Why the code below when finds the first matched section (Findings) stops looking for the other section (Complications)? If I add more sections to the OR list, it only finds the first match and ignores the rest. Really apprecite your wisdom! 

....
.....

while(<IN>)
{
undef ($/);
$string=$_;
$string =~m/(FINDINGS|COMPLICATIONS|(:)(.*?)(^[A-Z])/sgm; 

print "processing $file\n";
print OUT "$1$2\t$3";
}exit;

....
