Opal

The original name of software from CA Technologies that converts legacy output from mainframes and minicomputers into a graphical-based format. Now part of its Advantage Integration Server suite, the technology provides the development environment and supports 3270, 5250 and VT220 terminals and ODBC-compliant databases. Development can be done by drag and drop or by scripting in OpalScript or VBScript. A Telnet connection to the mainframe is provided and maintains a connection to the desktop allowing the Web browser or a Windows client with the software to have access to the newly formatted data. See green screen.
