PMDF MAIL and VMS MAIL users with VT-style terminals (and other terminals supported by the SMG$ run-time library) and DECwindows MAIL users can prefer to use the pop-up, "fill-in-the-blank" FAX addressing form provided by PMDF. When the special address FAX-FORM is used (IN%FAX-FORM from VMS MAIL or DECwindows MAIL), a pop-up form will be presented to the user. With this form, one or more FAX addresses can be specified by merely filling in the blanks. With the exception of DECwindows MAIL, this form will appear as soon as the address line (To:, cc:, or Bcc:) on which FAX-FORM is specified is entered. With DECwindows MAIL, the form will not appear until after the SEND button is pressed in the "mail create" window. Note that the pop-up form can also be invoked from PMDF SEND via the /FAX qualifier.
