MessageModal
MessageModal>message_text
Displays a message box containing the text specified in message_text. With this command the Message box is modal. This means that the script will not continue until OK is pressed. For non modal message boxes use Message.
To make a message box stay on top, set the variable MSG_STAYONTOP to 1. Likewise, setting MSG_CENTERED to 1 will ensure that the message box is always shown centrally on the screen.
You can set/get the height and width of the message box using the variables MSG_HEIGHT and MSG_WIDTH. Set the position of the message box using the variables MSG_XPOS and MSG_YPOS.
