Panels is a module that enables you to build windowing into an application. It comprises a set of routines that you can call from your COBOL programs.
The windowing features provided include overlapping windows, separate or synchronized updating of text and attributes, scrolling of text across a window and the creation of popup/pull-down menus.
Panels takes care of maintaining the areas of the screen that are overlaid by another window automatically. It is for programmers who require high performance screen handling facilities.
Panels enables you to create up to 65534 panels and to have 254 panels visible on the screen (subject to your machine having enough memory).
