Jacci,
I see Daniel posted your best solution. FWIW on my website are pages for VFP #defines for all the Word, Excel and Graph constants. There are also a couple of links on my links page to the MS Office developers pages.
>Thanks for the helpful hints. I wasn't sure how to pass True and False to Excel. Actually as I was composing this message it came to me to ERASE the file first, but thought maybe there was something I was missing. Guess not.
