While END will adequately close a statement, it is less clear than the use of the relevant, statement-specific ENDxx.
Thus, the statement-specific version is preferred to facilitate code maintenance and enhance clarity.
This rule is applied to the following operations: CASxx, DO, DOU, DOUxx, DOW,
DOWxx, FOR, IF, IFxx and SELECT groups.
