If you did > want to bale out early, then line 9467 would change to : In my programs I tend to put a catch-all in for cases like this which allows this case to go around the loop again, but also to exit the loop if exhausted:
9476 IF dv_start <= 1 THEN NEXT i : EXIT i The exit gets ignored unless the loop is exhausted. Not sure if it's good programming style, but it does seem to work. -- Dilwyn Jones _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
