After the starting frame's Go operation creates the FrameSource object, it sets the following frame attributes:

Name

Specifies the name of the frame

Datatype

Specifies the data type of the frame's return value

IsNullable

Specifies whether the return value is nullable

WindowTitle

Defines the title that appears on the frame's window

CurMode

Defines the frame's mode

WindowPlacement

Defines the location of the frame's window when the frame is called or opened

The sample application assigns the following values to these attributes:

/* Fill in the Frame Information */
test_frame_name = table_choices + '_frame';
test_frame.Name = test_frame_name;
test_frame.DataType = 'integer4';
        /* This is default */
test_frame.IsNullable = TRUE;
        /* This is default */
test_frame.WindowTitle = 'Edit Data For Table: ' +
        table_choices;
test_frame.CurMode = FM_UPDATE;
test_frame.WindowPlacement = WP_FLOATING;

Some frame attributes, such as StartMenu, are set later in the program (after the code creates the objects contained by the attributes). Other frame attributes are left at their default values. For an example of creating the StartMenu object, see How You Can Create the Frame Menu Items (see How You Can Create the Frame Menu Items).
