Description
New list creates a new, empty hierarchical list in memory and returns its unique list reference number.
WARNING: Hierarchical lists are held in memory. When you are finished with a hierarchical list, it is important to dispose of it and free the memory, using the command CLEAR LIST.
Several other commands allow you to create hierarchical lists:
- Copy list duplicates a list from an existing list.
- Load list creates a list by loading a Choice List created (manually or programmatically) in the Design enviornment List Editor.
- BLOB to list creates a list from the contents of a BLOB in which a list was previously saved.
After you have created a hierarchical list using New list, you can:
- Add items to that list, using the command APPEND TO LIST or INSERT IN LIST.
- Delete items from that list, using the command DELETE FROM LIST.
Example
See example for the APPEND TO LIST command.
