Default actions in MENU

When an MENU instruction executes, the runtime system creates a set of default actions.

Table 1. Default actions created for the MENU instruction
Default action	Control Block execution order
`close`	Created to execute `COMMAND KEY(INTERRUPT)` if used (can be overwritten with `ON ACTION close`) Default action view is hidden. See Implementing the close action.
`help`	Shows the help topic defined by the `HELP` clause. Default action view is hidden.

Window close events can be trapped with COMMAND KEY(INTERRUPT) clause.
