OE (On Expression)

The OE-command executes a list of conditional actions depending on the result of an expression block. A trial command is executed if its condition matches the result of the last expression in the expression block. You can define one or multiple actions for each condition to execute multiple trial commands for one condition. This is conceptually equivalent to having different trial sequences for different conditions.

To add a visual presentation to the current screen image, add the '+'-operator before the OE-command (see '+'-screen operator).
