next LABEL
nextThe next command is like the 
continue statement in C: it starts
the next iteration of the loop designated by LABEL:
LINE: while (<STDIN>) {
    next LINE if /^#/;     # discard comments
    ...
}Note that if there were a continue block in this example, it would
execute immediately following the invocation of next.
When LABEL is omitted, the command
refers to the innermost enclosing loop.
