Iterate a block prematurely

Daftar Isi

• next LABEL

• next

  The next command is like the continue statement in C; it startsthe 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 getexecuted even on discarded lines. If LABEL is omitted, the commandrefers to the innermost enclosing loop.

  next cannot be used to exit a block which returns a value such aseval {}, sub {}, or do {}, and should not be used to exita grep() or map() operation.

  Note that a block by itself is semantically identical to a loopthat executes once. Thus next will exit such a block early.

  See also continue for an illustration of how last, next, andredo work.
