# switch — Selective execution

The SWITCH construct is a control flow structure that allows for selective execution of code controlled via a multiway branch. It can be thought of as a series of IF constructs, each with the same value to compare from.

If the value of a SWITCH statement equals the value of an embedded CASE statement, the control flow continues with the execution of that CASE statement. Otherwise, the control flow continues with the execution of the embedded DEFAULT statement.
