What is an array?
A one-dimensional array in 4D is similar to a list of items that exists only in memory. Each list (which can be thought of as a column) always contains data of the same type.

Arrays are a powerful programming tool. They can be used as language objects to solve code problems, or used to create and manage form objects such as drop down menus. Connectivity using 4D Open or 4D Oracle demands full understanding of their use.
