OCI Basic Display Set (BDS)

Publication 8520-6.6 - August 1999

Also include with the Basic Display Set source code are three forms
used as templates to create the majority of the other display forms in
this Visual Basic project. These forms are found with the rest of the
Basic Display Set forms in the FRM sub–directory of your Basic
Display Set source code. We call these “master” forms. They are:

MASTER.FRM – a highly comment form typically used for
reference only when building other forms.

MASTER0.FRM – use to build forms with no cursor movement

MASTERM.FRM – use to build forms that require cursor
movement

The following section will walk you through the development of a
screen using a MASTER.FRM.

Making a Copy of MASTER.FRM

Since the master forms are a good place to start for creating any
additional screens in the Basic Display Set, it is probably a good idea
to use a copy of these forms instead of editing them directly. This
will always give you a clean starting point for any additional forms
you need to create.
