The purpose of a loop statement is to perform a repeated execution of a statement sequence. It is only terminated upon execution of an EXIT statement within that statement sequence.
loop_stmt ::= LOOP stmt_seq END |
Example:
LOOP
ReadInt(i);
IF i<0 THEN EXIT END;
WriteInt(i)
END
Loop statements are useful to express repetitions with several exit points. They are also useful in cases where the exit condition is in the middle of the repeated statement sequence.
