next
next - iterate a block prematurely
next LABEL
next
The 
next
 command is like the 
continue
 statement in C; it starts
the next iteration of the loop:
    LINE: while () {
        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.
