I agree wholeheartedly. I've been in situations where the same set of
indicators is used for all subfile control functions (SFLDSP = not SFLCLR,
SFLDSPCTL, SFLEND, etc.). I would save the block of contiguous indicators
in a suitably long variable when leaving the subfile via an option. Then
other subfiles within the option can use their own set. And all that is
needed is to restore (MOVEA) the previous set on redisplay coming out.

Hope that made a little sense!  :-)
