Fields
------
The fields unit has evolved from IBM's computer that came out just before
the PC, the IBM System 23/Datamaster. The S/23 was the first desktop size
computer which supported full-screen editing. The method of handling user
input for programs is easily transportable on the PC and provides a uniform
and proven method of interacting with the user.
The Fields unit allows a (pascal) program to define strings which describe
the location, length, visual attributes and characteristics of fields which
the user can input data into. The implementation is clean and should prove
to be very functional. The Fields unit was originally an include file
under Turbo v2 & 3 and is now enhanced as a unit in Turbo Pascal v4.
Fieldemo
--------
The Fieldemo program provides an elementary idea of what can be done in
defining input screens. This approach has been used on screens which have
more than 128 fields for the user to input data on one screen.
BoxDemo
-------
The BoxDemo program shows how a screen made-up of field titles and
definitions for input fields is automatically turned into the field definition
strings required by the Field_In and Field_Out routines. The screen area
when the boxed/windowed field area is to be written is saved using the
routines in Pwindow.Arc. The screen area is restored as shown in the
BoxDemo program.
