Common name for a group of commands which break the linear structure of the program I'm looking for a name of a group of all commands which are break the linear structure of the program.

In C PL, they are: goto,return,break,continue. C++ also contains throw.

Perl has last,next,return. 

Is there a common name for those groups of commands? Where can I read about those kind of commands?
These are control flow statements. There is a quite a large list of them on their Wikipedia page.
