The ACUCOBOL-GT release materials include many sample programs and their source code. Many of these programs demonstrate ACUCOBOL-GT's GUI capabilities. We recommend that you study the source code for these programs to gain a better understanding of how ACUCOBOL-GT GUI objects are programmed. You can find these programs and their source code in the %PUBLIC%\Documents\Micro Focus\extend x.x.x\sample directory.
Included among the sample programs is a program called "message." This program provides basic message-box support on any host. The message program calls the host operating system's message box handler when one is available. Otherwise the run-time provides a simulated, character-based message box. See the comments in the program source for additional details.
