Deleting Old Prescriptions
Most prescriptions need to be held for two years, but this depends on your state's requirements.  For example, to delete prescription that are over two years old do the following:
 
Open the database with the highest level password and go to the Entry screen.
 
Select Find from the Mode menu.  Click in Prescription Dispensed Date, type the “<“ sign and today’s date but two years less (i.e. fro 8/22/97 you would enter “<8/22/95”) and press enter.

Review the found set of appointments, if any.  To omit records from the set select Omit from the Select menu.  Finally to delete the entire found set select Delete All from the Mode menu.  Warning:  This is a permanent action and cannot be undone!
