The COBOL run-time system depends on a terminfo database being available and providing various terminal details to support the Adis module. The run time system regards some details as essential, and returns a run time error if they are not available. It regards all others as optional (making use of many of them and ignoring the rest). The following tables list entries in a terminfo terminal description that are recognized by the COBOL system. See your UNIX system documentation for details on the system terminfo database and how to specify terminal capabilities.
