DO-END Command Sequence

DO
Requires that the group of commands that follow is to be treated as a single unit. That is, the group of commands run as a result of a single IF command. The END command ends the set of commands. A command following a DO must begin on a new line.
END
Specifies the end of a set of commands initiated by the nearest unended DO. END must be on a line by itself.

Restriction: Do not use continuation characters in the DO-END sequence; they are taken as a null command or cause unpredictable results.
