Well, now that you've explained... I have no idea what you are talking
about... sorry.

I'm working hard at getting a clear example... especially a working
one or I'd try to outline.. what I'm doing.
But briefly put: I'm walking through a large list one line at a time.
Most often a single line of the large list (each line is one filename).
will be sent through the disp table.
For some situations... each line is stored in an array, and that array
is sent thru the disp table. So all can be displayed and user can
see what action is appropriate. Usually just one file in the array
will be acted on, but sometimes it will be all of them.
There will be one default_action that gets used most often by a wide
margin, than maybe 3 other sub function that the table points to.
Oh, and a couple of others... to just continue with no action or quit
altogether.
Those 4 named sub functions (or so) and 2 (continue,quit) I guess, are
the handlers you asked about.
