Sent to the current card
When Oracle Media Objects receives a message it cannot interpret, it sends a cantUnderstand message to the current card You can write a handler to intercept this message before a standard "Can't understand" alert box (for example, "Syntax error," "Object not found") appears.
Imagine that you have a stack of library handlers called "My_Handlers". The following stack script checks whether a command that Oracle Media Objects could not interpret is contained in "My_Handlers" and then reminds you to library that stack.
on cantUnderStand aaa
aaa is "my_handler3" then
