Switch Step

Use the Switch step to cause the program logic to branch to one of a number of cases based on the evaluation of a specified expression.

Switch Customizer Window

A case is a method for providing script logic based on the value of a variable at a point in time. You can assign one case for each value. The Switch step lets you define any number of case output branches. You can then create a separate script logic for each branch.

Note	Use a subflow in a script (instead of a redirect) to transfer a call to another script.

The Switch step supports switching based on the following variables:

Integer—Comparison of integers
String—Comparison of string variables (case insensitive)
Language—Comparison of language variables

Note	The language comparison will attempt the parent language before falling back to default. For example, a match for L[en_US_Judy] will first attempt to match from the following list: {L[en_US_Judy], L[en_US], L[en]}, and then return “Default” if no item in the list matched.

The type of switching is automatically determined by the type of the specified expression.

Steps that you add following a specific case output branch execute if the integer, string, or language expression you specify for that case is equal to the global expression defined in the Switch Expression field.

The Default branch of the step allows you to handle cases where none of the branches matches the expression.

The following table describes the properties of the Switch customizer window:
