No, I'm looking for a limited version of the editing capabilities that
modern command line interfaces have; namely, the ability to "preload"
the input area and to allow the user to edit it.
# Re-constitute the natural form of city/state/zip
# from the "terse" form that we already have.
my $default_input = foo("IN-NewDurhamTwpMetro66765");
# Now $default_input contains "New Durham Twp Metro, IN 66765"
# Call my get_input routine, which pre-loads the input area
# with the text in $default_input and permits the user to
# edit the default text, exactly the way modern shells allow
# you to edit the command line.
print "Enter city, state, and zip: ";
my $input = get_input( $default_input );

Enter city, state, and zip: _ew Durham Twp Metro, IN 66765

The underscore indicates where the cursor appears: under 'N', the
first character of the input field. At this point the user can edit
(e.g. forward-cursor to 'Twp' and change it to 'Township').
[In the above example, I'm looking for the implementation of
get_input(), *not* of foo()!]
