Like the system object datatypes, enumerated datatypes are specific to PowerScript. Enumerated datatypes are used in two ways:
As arguments in functions
To specify the properties of an object or control
You can list all the enumerated datatypes and their values by selecting the Enumerated tab in the Browser.
You cannot create your own enumerated datatypes. As an alternative, you can declare a set of constant variables and assign them initial values. See “Declaring constants”.
A variable of one of the enumerated datatypes can be assigned a fixed set of values. Values of enumerated datatypes always end with an exclamation point (!). For example, the enumerated datatype Alignment, which specifies the alignment of text, can be assigned one of the following three values: Center!, Left!, and Right!:
mle_edit.Alignment=Right!
Incorrect syntax
Do not enclose an enumerated datatype value in quotation marks.
If you do, you receive a compiler error.
Enumerated datatypes have an advantage over standard datatypes. When an enumerated datatype is required, the compiler checks the data and makes sure it is the correct type. For example, if you set an enumerated datatype variable to any other datatype or to an incorrect value, the compiler does not allow it.
