hi I obviously read the wrong books because I'm not able to find out how this "construct" is called: 
 MAIN_LOOP: 
 for my $number_to_check (3 .. 200)
    {
...

[download]
So my questions about MAIN_LOOP:
- how do you call 'that'?
- how does it work?
- what do you think about its usage? (none of the books I read use it, but I've seen other code that use it often)

thanks
ben
