Basic - loop with condition on the beginning: do while loop, while wend

condition testing is done at the beginning of the loop. before each iteration the condition is tested, if it is was true. before the first iteration is a condition test, the use of this loop is excellent in situations where perhaps we don't need to execute the cycle.
