or you can use "exit" if you are using a loop, if you are not sure. personally i have never use return before, i always use exit |

use return. imagine your procedure like a loop. now sub exit for return its like the result command in functions. it quits the procedure, and continues along the mainline. if you use return not in a procedure, it quits your prog. -Z |
