USING AN ENABLE APPLICATION
DELETE Considerations for Applications with Several Boxes
1. Retrieve the records that you want to delete by requesting
any suitable read operation.
2. If any records appear that you do not want to delete, replace
these records with the default record.
3. Press Shifted F12 to delete the records shown on the screen.
If the application encounters an error during the DELETE BOX
operation, it highlights the fields of the record in error. The
application then displays the following prompt at the top of the
screen:
Continue processing, Y/N, F1
If the application displays this prompt, you must enter either
the character Y (to indicate that you want to continue) or the
character N (to indicate that you want to stop) and then press
F1. If you enter a Y, the application continues the DELETE BOX
operation beginning with the record that directly follows the
record in error. If you enter an N, the application stops the
DELETE BOX operation. In this case, the application has already
deleted any records that appear above the record in error. If
you request an UNDO operation at this point, however, you can
return the data base to its previous condition.
DELETE Considerations for Applications With Several Boxes
If you delete a record from a containing box, you can no longer
use the application to retrieve the matching record (or records)
for the nested box. If this is a problem for your application,
do the following:
1. Use any read operation to retrieve the record for the
containing box.
2. Use an appropriate read operation to retrieve the record (or
records) for the nested box.
3. Delete the record (or records) displayed in the nested box.
4. Repeat steps 2 and 3 until the application does not return
any records as a result of the read operation.
5. Delete the record in the containing box.
