in thread Fetdching filenames starting numbers.

There's a "return" statement in nearly every procedural programming language supporting subroutines. It causes a subroutine to be stopped and to return a certain value to the caller.

sub foo { return 1 }; $var = foo(); #$var is 1 sub bar { print "AAA"; return 1; print "BBB"; #will never happen, for 'return' has # stopped this sub } $var = bar();

The breaking character of return is not present in all languages, i know ugly Pascal doesn't have a return statement and you cannot exit a sub from the middle.

These are the very basics, try a good book to start!
