 from \fBinitscr\fR when an error is detected, rather than exiting.
 It is safe but redundant to check the return value of \fBinitscr\fR
 in XSI Curses.
+.PP
+If the TERM variable is missing or empty, \fBinitscr\fP uses the
+value ``unknown'',
+which normally corresponds to a terminal entry with the \fIgeneric\fP
+(\fIgn\fP) capability.
+Generic entries are detected by \fBsetupterm\fP(3X) and cannot be
+used for full-screen operation.
+Other implementations may handle a missing/empty TERM variable differently.
