Ken -

This is more like what I'd "like" to do. In the DOS app there are usually to many fields for the 80 char limit so there can be as many as six pages (tabs or left/right arrow). The most used are on the main page (Part#,Qty,Price,etc..) but if needed next page might be vendor, manfacturer, discount, type, etc.. and I've never had a complaint. However, that's how they learned to use the program.
So having to scroll right doesn't bother me that much, but in my system the line total always display as the far right field, I'm not sure a grid could do that...
