4GL Access: R

When a frame receives a user event, this attribute contains the value assigned to the messagefloat parameter of the SendUserEvent call.

Use this attribute in a UserEvent block to obtain the messagefloat parameter value sent to the frame by the SendUserEvent call for that user event.

Because messagefloat is an optional parameter for the SendUserEvent method, this attribute may not have a value. In such instances, the default is zero.
