Don't forget dragDrop :-) Seriously, this is an old question that keeps coming back, and a prime candidate for either an engine-level field "mask", or a community effort to write a behavior script that handles the corner cases and is readily available for download. A bit of searching turned up bits and pieces as far back as 2002 in my archives, but the combination of these two emails seems to do the trick: <http://lists.runrev.com/pipermail/use-livecode//2002-October/008411.html> <http://lists.runrev.com/pipermail/use-livecode//2003-September/022375.html> (best to follow these links, as it looks like the post-rename archives are slightly misaligned) While it does a bit too much for Charles' use case (formatting number for display) the underlying logic is sound. Thanks to Ken Ray for writing the RegEx back in 2002 to split a number into a sign, integer and decimal part. <http://lists.runrev.com/pipermail/use-livecode//2002-September/008030.html> Jan Schenkel. ===== Quartam Reports & PDF Library for LiveCode www.quartam.com ===== "As we grow older, we grow both wiser and more foolish at the same time."
