Jim,

Thanks for all your help on that last episode of updating fields. I finally understood what you were meaning after some HOURS of thought and study. Now I have a functional form that I can make improvements on. Thanks again.

To contrl the output of the zeros you need to build your own creation of the text file as I showed. You should be able to use yur afields() array to build the ?'s inside of the scan loop. You may need to make it a series starting with one ? and then followed by a series of ?? for each field so you can chekc the afields array for the data type to deterimine the separators and delimiters to be be used.
