ActionKey (Screen function)

Return name of key that activated last screen read (Screen class)

Syntax

%key = screen:ActionKey

Syntax terms

%key	A declared ActionKey enumeration (see below).
screen	A reference to an instance of a Screen object.

ActionKey enumeration

Valid values of this enumeration are Enter and Pf1, Pf2, and so on through Pf24. The value that is set initially is Enter.

Usage notes

You can use the ActionKey class ToNumber method to convert ActionKey enumeration values to a numeric value: the integer that remains after the key name is stripped of its "PF" prefix. For Enter, the numeric value is 0. These values are useful in a value-testing loop in conjunction with the User Language Jump statement.
