Suppose you have a list of students and you receive an update file containing their new grade point averages. You can use the UPDATE command to update your list of students:

use STUDENTS order STU_ID

use ? alias UPDATES

update on STU_ID from UPDATES replace GPA with UPDATES->GPA RANDOM

The ? option in the USE command displays a dialog box from which you can pick the new file. The file is always opened with the alias UPDATES.
