2.06 Grouping Statements
A DO group is a set of statements that start with the word DO and finish with the word END.
Generally any executable statements can be included within a DO group, including other DO groups.
Within the language structure a DO group is treated as if it were a single statement. What this means is that generally anywhere where a single statement is acceptable then a DO group is also acceptable.
The DO statement may be modified by the words WHILE or UNTIL to make a conditional loop.
DO ... END
Defines a block of statements.
