next LABEL

     next    The next command is like the continue  statement  in
             C; it starts the next iteration of the loop:

                  line: while (<STDIN>) {
                       next line if /^#/;  # discard comments
                       ...
                  }

             Note that if there were  a  continue  block  on  the
             above,  it  would  get  executed  even  on discarded
             lines.  If the LABEL is omitted, the command  refers
             to the innermost enclosing loop.
