Dear Jon: I am not sure about your version. I am using TOPAZ7.51. The Technical reference says VFile supports Search function but the Readme.751 tells the other way. My way to set the Appendmode of the VFile to Ascending order then append the Dbase file to the VFile and write a Binary search on the VFile. This will take you less than an hour to do it. But I do have a problem in using Vfile. The VFile has to be active at Design time. If it is not active at design time and is set to active during run time, it will look like to be working but not quite. I believe the memory allocation will not be done properly if you set VFile active at run time. If you see funny things after you append a large file into the VFile then make the VFile to be active at design time. This is my way to solve the problem. Does any one have a better idea?
