An introductory frame is a frame that is displayed briefly when your application starts, and is then cleared from the screen and replaced by the frame(s) you specify as arguments when fmli is invoked as the initial frame(s) to open. The introductory frame will be displayed again briefly when the user exits from your application.
The introductory frame is defined with four descriptors normally used to define a text frame. Note, however, that the defaults are different when they are used in an initialization file.
The introductory frame descriptors are described below. Either the title or text descriptor must be included in the set of introductory frame descriptors.
A definition for an introductory frame is simple, as the following example shows:
title="WELCOME TO" text="My Application Copyright (c) 1989 My Software, Inc. All rights reserved." rows=5 columns=25Backquoted expressions, containing calls to built-in utilities, may also be used, as in this line:
text="`readfile DEF_FILES/myintrotext`"
which will cause the text frame definition file myintrotext to be read from the directory whose alias is defined to be DEF_FILES, and passed to the text descriptor as the argument. (See ``The alias file'' for more information about how to define aliases.)
