GUI ScreenIO for Windows

Getting Started with GUI ScreenIO

Once you've installed GUI ScreenIO on your system, you need to do 4 simple things before you can use it.

1 Set up your GUI ScreenIO profile

The panel editor uses an application profile to set the defaults you wish to use when you create a new panel, and to specify the locations where your panels will be stored.

2 Customize GS.COB for your compiler

The GUI ScreenIO runtime DLL will work with virtually any 32-bit COBOL compiler.  We handle this by providing an intermediate COBOL module, GS.COB, that lets your compiler call the GUI ScreenIO runtime DLL.

Modify and compile GS.COB.

3 Compile and test your first GUI ScreenIO application

We've provided a sample application for you to study and compile.  Once you've successfully compiled and test it, you're ready to begin using GUI ScreenIO.

View the sample GUI ScreenIO application.

4 Start Development

Start using the Panel Editor to create your panels.

Remember that each application must start with a MAIN panel.  You must call a main panel before any other GUI ScreenIO Call.

You create a main panel just like any other panel.  Just Select STANDARD MAIN as the type.

This Main Panel is the container in which your application "lives".  The main must be the first panel called by your application.  

If you are converting a Legacy ScreenIO application, use the conversion utility, and remember to add a Main panel to your application's main program.

For new development, consider using our Code Generator, to create consistent programs.  It gets you over the writers block.
