If you give the commands just like the example I give you, obviously adapting file names and field names, that will create a so-called "cursor" - a temporary table. Visual FoxPro will save it on disk with some random name, but delete the file as soon as you close the cursor. Many different Visual FoxPro commands work with cursors just as well as with tables. In this particular case (preparing data for reports) they have the following advantages: (1) cleanup is simpler. (2) great for multiuser access; if two users use the same commands, different temporary files on disk will be created, and there will be no conflict. Of course, you could also create a random filename yourself, but that takes more work.
