You are given the option to create a new version  of the database file. This allows you to recover from editing errors by deleting the most recent version of the database file, e.g., $ DELETE TESCAL.DBC;. WARNING: Before you inadvertently delete a database file that you want, check to see what versions you have and when they were created, e.g., $ DIR/DATE TESCAL.DBC. Once you are happy with the current version of your database, you should purge  the earlier versions, e.g., $ PURGE TESCAL.DBC.

To edit you must define one or two key  parameters which uniquely describe a record of data. In some tables shot will be the key. In others, where shot is not unique, shot and time, may be keys. You can have either one or two keys.
