What I do is that I take that string and use StrAToI to get a number, if that number is 0 then it means that the string entered was invalid. I mean what is the big deal to try to write some extremely complex routine that allows users only to enter valid number strings. Let users enter what they want (eg "1-2.3-...24----24") but then react accordingly. It will save you precious space. /C -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
