Thanks for the replies. I was really after something like an alarm clock, where you could set a particular time and it would 'go off'. But more like a stop watch, where a timer would 'count down' from a preset time and sound an alarm continuously until it was shut off. I suppose I could break open the piggy bank and buy an oven timer, but why do that whan I have a perfectly good PC and you guys? ;-> * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
