Hello, and what does a ";" ? It is the short form of ?CompoundExpression "expr1; expr2; ... evaluates the expri in turn, giving the last one as the \ result." The three commands in a single Do[] loop will work like one Do[ Print["I must read the"]; Print["manual more carefull."]; Print["All 1470 pages are extreme usefull."], {200} ] because the commands are grouped by a CompoundExpression[] that collect several expressions into a single one.
