3. Note The programmer must make sure that no endless loop is caused He does this by changing the condition in the instruction part of the loop for example by counting up or down one counter Example WHILE counter lt gt 0 DO Varl Varl 2 Counter Counter 1 END_WHILE The WHILE and REPEAT loops are in a certain sense more powerful than the FOR loop since one doesn t need to know the number of cycles before executing the loop In some cases one will therefore only be able to work with these two loop types If however the number of the loop cycles is clear then a FOR loop is preferable since it allows no endless loops 2 17 REPEAT loop EXIT instruction Languages The REPEAT loop is different from the WHILE loop because the break off condition is checked only after the loop has been executed This means that the loop will run through at least once regardless of the wording of the break off condition Syntax REPEAT lt Instructions gt UNTIL lt Boolean expression gt END_REPEAT The lt Instructions gt are carried out until the lt Boolean expression gt returns TRUE If lt Boolean expression gt is produced already at the first TRUE evaluation then lt Instructions gt are executed only once If lt Boolean_expression gt never assumes the value TRUE then the lt Instructions gt are repeated endlessly which causes a relative time delay i Note The programmer must make sure that no endless loop is c
