Switch data type

You can use the switch data type to store and manipulate Boolean values. The value of a switch can be used anywhere a test expression is permitted.

Switches are automatically initialized to false when they are created. You should explicitly initialize switch variables before using them. Forgetting to initialize (or re-initialize) variables is a frequent source of errors.

You can initialize a switch when you declare it:

  local switch is-special-case initial {false}

You can set the value of a switch variable to a Boolean constant (true or false) or to the value of a switch expression:

  set is-special-case to true
  set is-special-case to quantity > 50 or quantity < 0

You can use the following operators with switch variables:
