Ah.. thankyou.

So what I am reading between the lines here is the OR ability in regex.. which I iether never knew, or knew and forgot.

So the next question (and you dont have to answer it cos just pondering outloud) is: where does the OR finish and the next thing begin? 

$string = 'this is a bing'; # sample strings..
$string = 'bing is my name';
$string = 'cows go bonging';
$string = 'cows go bang99'; 

$string =~ m/^bing|bong|bang\d\d/;

Would I need to put ^ infront of each OR case of I want them to match at the beginning of the line only?
Similarly if I want all to only match if the end with \d\d do I include it at the end or in each case?
How does it know the end of the start of the first OR case and the end of the last OR case?
