MessageBox(style, title, message_set, message_num, default_txt [, paramlist])

In addition, in the PeopleSoft Pure Internet Architecture the Message
Severity dictates how the message displays:

If the message has a severity of Warning, Error or Cancel, the message is
displayed in a pop-up dialog box with a single OK button regardless of the
value of the style parameter.

If the message has a severity of Message and style is %MsgStyle_OK (0),
the message displays in a pop-up dialog box with the single OK button.

If the message has a severity of Message and style is not %MsgStyle_OK
(0), the message displays in a separate window
