ACTION_STATEMENT

An action statement.

Description

This statement can be specified within a block to trigger an action whenever that block is left implicitly. This statement is not taken when the block is left explicitly with the leave block keywords.

Note that you cannot use a leave block statement with a response to termination response definition.

This statement cannot contain a block, nor can it contain a reference to any action routine or subroutines that contain a block. If it does, an irrecoverable runtime error may occur, and no error message will be generated.
