FRx & F9 are not really the same animal. The functionality is quite different as well as the method of creating statements. I do have a site using FRx on macola SQL & it works quite well. Version 5.5, tho. I did have to get the SQL FRx when we converted from btrieve to SQL, so you definitely cannot use 4.18. Macola no longer supports or sells FRx, so you'd need to ask FRx sales if the version you can buy today will work with macola or not. I suspect not, because the FRx refresh still needs to be run in order to generate reports. That function may have been written by macola or by FRx specifically for macola. F9, on the other hand, says they still intend to offer the product for ES even though macola doesn't intend to sell or support it since they want to use the excel add in.
