Message

Message(MSG1, MSG2, ..., MSGn), Msg(MSG1, MSG2, ..., MSGn)
With Message (short form Msg) any identifiers are agreed upon as message names. The messages can then be used just like the firmly defined system events SELECT, CURRENT, NON_CURRENT, ... can be specified as triggers for an instruction sequence. In addition, a message can be sent to other Windows objects using SendMsg, PostMsg or ReturnMsg, and this is exactly what triggers the execution of the statements associated with the message.
