Including a Browse Window in a Screen

You can create a screen that contains a Browse window. By including a Browse window in a screen you give the user a one-to-many display of fields, similar to Figure 1. However, because a Browse window is not a screen object, youneed to define a child window for the Browse and then write a program to manage user interactions with the Browse window.

Fig. 1: Parent and child window schema for including a Browse window in a screen.

You cannot add GET fields to a parent window and have them interact with fields in a child window, but you can add GET fields to a separate screen, and then generate the two screenstogether in a screen set. The generated screen set can act as a single screen because the #WCLAUSES generator directive allows you to define one screen as a child window of the other.

Use the following general procedure to create a screen with two child windows: a Browse window and a window with GET fields. The section following the general procedure elaborates on these steps by providing aspecific example that shows how to create a one-to-many screen.


To create a screen that contains a Browse window and GET fields:

1. Set up the environment for the screen set.
2. Create the parent screen that will encompass the GET screen and the Browse window.


3. In the setup code for the parent screen, define a window with the attributes you want the Browse window to have, but don’tactivate the window. For example:

DEFINE WINDOW wbrowse ;
FROM 13.85, 3.00 ;
TO 22.85, 90.00 ;
FONT "MS Sans Serif", 8 ;
NOFLOAT ;
NOCLOSE ;
NONE ;
IN WINDOW wmain


Wmain is the name of the parent window as specified in the Screen Layout dialog box for the parent screen. To obtain the FROM and TO coordinates, draw a rectangle in theparent window where you want the Browse window to be. Note the top, bottom, left, and right positions of the rectangle as displayed on the status bar.

4. Include a BROWSE command in the setup code. For example:

BROWSE WINDOW wbrowse IN WINDOW wmain NOWAIT SAVE

5. Create a separate screen for the GET fields.
6. In the setup code for the GET screen, include the following command:...
