The Exit Do statement is used to trigger a forced exit of a loop Do ... Repeat While . The program flow jumps to the statement immediately following the Repeat While loop termination brand . In the case of nested loops only loop SalirHacerafecta is in the process when it comes to this output instruction. Use before or after a bucleHacer ... Repeat While no effect to be meaningless .

SalirHacer can be found at any point between the Do and Repeat While . Normally go after evaluating a situation that evolves as does the loop, and that is the trigger for the output.

Having SalirHacer order will allow us to introduce a variant of the instruction Do ... RepetirMientras . This variant is the same instruction but while the output condition . The syntax is the familiar :

do
Instruction 1
Instruction 2
.

.
Instruction n
repeat


It is clear that within the loop must be an outlet through a SalirHacer because otherwise the number of repeats would be infinite .
