&SYS.TERM.EXTHI The &SYS.TERM.EXTHI system variable indicates whether the terminal from which
the NCL procedure is executing supports extended highlighting. &SYS.TERM.EXTHI
is initially set when you log on to a terminal.
If the terminal supports extended highlighting, &SYS.TERM.EXTHI is set to 1;
otherwise, it is set to 0 (zero).
Testing of device attributes from within an NCL procedure displaying full-screen
panels is not normally required. Panel Services automatically suppresses the
generation of extended highlighting data streams if they are not applicable to the
device to which the panel is being sent.

See also &SYS.TERM.EXTCO, which indicates if the terminal from which the NCL
procedure is executing supports extended color.
