Correct. A serious program should not be fooled by this. Not every screw
up is caused by users, especially on old unices, so the usual "don't do
it" argument doesn't always apply. Usually it's safe to assume that the
terminal is 80x25.

That's the actual code:

    SLtt_get_terminfo ();

   /*
    * If the terminal in not in terminfo but begins with a well-known
    * string such as "linux" or "xterm" S-Lang will go on, but the
    * terminal size and several other variables won't be initialized
    * (as of S-Lang 1.4.4). Detect it and abort. Also detect extremely
    * small, large and negative screen dimensions.
    */
    if ((COLS < 10) || (LINES < 5) || (COLS > 1024) || (LINES > 1024)) {
        fprintf (stderr,
                 _("Screen size %dx%d is not supported.\n"
                   "Check the TERM environment variable.\n"),
                 COLS, LINES);
        exit (1);
    }
