Use enumerated type controls to give users a list of actions from which to select. An enumerated type control, or enum, is similar to a ring control of strings. However, with an enumerated type control, the value is a string instead of a number as with ring controls. For example, use an enumerated type control to select the cases of a Case structure.
The enumerated type control data type is unsigned byte, unsigned word, or unsigned long. Right-click the enumerated type control and select Representation from the shortcut menu to change the data type of the control.
