The EXIT statement exits the current iteration of a loop, either conditionally or unconditionally, and transfers control to the end of either the current loop or an enclosing labeled loop.
An EXIT statement must be inside a LOOP statement.
Name that identifies either the current loop or an enclosing loop (see "Basic LOOP Statement").
Without label, the EXIT statement transfers control to the next iteration of the current loop. With label, the EXIT statement transfers control to the next iteration of the loop that label identifies.
Without this clause, the EXIT statement exits the current iteration of the loop unconditionally. With this clause, the EXIT statement exits the current iteration of the loop if and only if the value of boolean_expression is TRUE.
