4D choice lists have a number of useful uses. They provide:
- A way to choose among multiple values while entering data into a field.
- A way to store the items for drop down lists.
- A way to store the names of the individual tabs for form tab objects.

Choice lists have one major disadvantage: they are stored in the database’s structure file. If you give the end-user the opportunity to edit these lists, their values will be overwritten the next time you send them an update.
This technical note will discuss a few applications of non-hierarchical choice lists and explain a way to
store their values in the data file so that you can update users without overwriting their list values.
