Explicit scope termination

The scope of a statement may be explicitly terminated by using its associated scope terminator. A statement written with its explicit scope terminator is a subset of imperative statements and is termed a delimited scope statement.

An explicit scope terminator terminates the scope of:

1.	the most-recently preceding unterminated statement having the statement-name for which that scope terminator is defined, and

2.	any unterminated statements that appear between that statement-name and the explicit scope terminator.
