REPEAT Statement
<![CDATA[
To loop over a set of statements until a post-statement condition is met, use the REPEAT statement.
[begin_label:] REPEAT
statement_list
UNTIL search_condition
END REPEAT [end_label]
The statement list is repeated until the search_condition is true.
A REPEAT always enters the loop at least once.
statement_list consists of one or more statements.
A REPEAT statement can be labeled.
end_label cannot be given unless begin_label also is present.
If both are present, they must be the same.
