The ACUCOBOL-GT runtime module for MS-DOS systems doesn't use a terminal database file when the standard DOS monitor is used. If you choose to use a terminal (such as the VT-100), rather than the standard DOS monitor, you need both an alternate runtime module and a terminal database file from Acucorp. These can be requested from your Customer Service Representative at Acucorp. Be aware that your programs execute less efficiently with this combination than with the standard MS-DOS monitor and the standard MS-DOS runtime from Acucorp.
