## 6.3.1. Special sets and targets

The `timer`, `match` and `regex` commands may specify (by omission) the default set. This set is exactly like any other set, except that it is automatically cancelled after the occurrence of any event. It may be explicitly named by using the empty string, (ie, `""`).

The `timer`, `match` and `regex` commands may also specify (by omission) the default target. This target, whose name is also the empty string, has the special propery that it always refers to ``the statement immediately following the next wait statement.'' That is, if the target of any event is the default target, the occurrence of that event just causes execution to continue starting with the statement following the wait statement.

Finally, when `all` is used with the ``cancel'' command, all sets (i.e., all pending events) are cancelled.
