Suppose that we wish to see all the subscriptions entered for a particular subscriber. First, find the subscriber record with the QUERY and FIND functions. Then, press the NEXTFORM key <F7>, and form displays a blank subscription form. To find the first subscription record (for this subscriber), press the FIND key <F3>. Pressing the FIND key <F3> again displays the next subscription record, and so on, until all the records have been displayed and the message No more appears.
The QUERY and FIND functions may also be used to search for a particular subscription record and, once such a record is 'found', the UPDATE and STORE functions may be used to change it, or the DELETE function may be used to remove it from the data file altogether. The ADD function could also be selected to add new subscription records to the data file.
