This Built-In Function is designed to delete a permanent or temporary working list.
It is good practice to specifically delete temporary lists.
File DC@F80 in the LANSA data library is used to store saved list details. This file should be considered in your backup and restore procedures.
Deleted record space in file DC@F80 is reorganized and removed during a normal LANSA internal database reorganization. This reorganization also deletes any temporary lists that have exceeded their retention period.
You can reorganize file DC@F80 to free deleted record space at any time by using the IBM i RGZPFM (Reorganize Physical File Member) command. Use DC@F80V1 as the sequencing logical view.
The backup and recovery of data area DC@A08 and database file DC@F80 (and its logical views DC@F80V1 and DC@F80V2) is your responsibility.
Movement of DC@F80 or saved lists between machines or between environments is your responsibility.
A list has been saved. It contains a list of contacts that need to have their information updated in the database. This user is in a telemarketing role. The user looks at a record, calls the contact and ensures the database is up to date. If a change is necessary the user changes the information and updates the database.
The list has come from a job that has checked the date of update of each contact. If the update date is more than NN days the record is put into a list. The list is then saved.
When the list has been processed the saved list is deleted.
