With the ACUCOBOL-GT runtime, users who need to access query or look-up services have a way to quickly and easily obtain important information. The front end consists of WML- or HTML-compliant software like a mobile device browser that can communicate via CGI with a Web server. The communication link is TCP/IP. On the back end, you have your COBOL application, a COBOL-based CGI program for interfacing between the mobile device and the COBOL application, and the ACUCOBOL-GT runtime. You can use this technology for applications in which you initiate a request for information, for example, up-to-the-minute currency exchange rates or the status of product shipments.
