Why would you want to clear a string in the first place? Second question would be what you consider a cleared string? Should it be a list of only spaces? Or termination characters?

Most LCD libraries have something like an lcd.clear or lcd.clr command which clears the LCD.

i dont want to clear the lcd i want to clear the string that i can us it again. after clearing he should been like at the beginn.

So what do you expect then clearing the string will do? It wont have any effect on the state of your LCD.
