These are the c-hooks into the ACCELL amgr to use an editor
to edit TEXT fields in the unify database. The file 'fedit.fs'
is the accell forms script that all forms call to fire off the
editor. 'fedit.fq' (uuencoded) is the form definition itself.
Several global variables need to be set for fedit to work, these
are documented in 'fedit.fs'.

The various functions provide the following capabilities:

	edit_txt() : Provides an interface to an editor (or any other
		     program) to modify text/binary fields. The 
		     routine will write the text field out into a
		     temporary file, passing the filename as an
		     argument to the editor program. The fields will
		     be null padded to an allocation boundary when 
		     written back to file.dbv. 

	display_txt() : Will display the first "line" of the 
		        text in the text field into the 
		        supplied screen string field.  The string
			passed as the screen field argument must be
			pre-allocated to whatever display length
			you want.  The easiest way to do this is
			to assign a strings of spaces to it just before
			the call to display_txt().

	show_txt() : A read-only version of edit_txt().

	to_upper() : Convert the supplied string field to UPPER case.

	week_day() : Return the day of the week of today. (0=Sunday,
		     6=Saturday).

	day_of_week() : Return the day of the week of the supplied
		        unify short date field.  We primarily use this
			to detect Saturdays and Sundays when users are
			entering due dates or tickler dates.
