Does anyone know of a quick and reliable way of detecting
whether ANSI.SYS has been installed?

Also, if ANSI.SYS is not installed, the results of prompting for a cursor position report would yield random results. A "slow hack" (no flames intended): Make sure that you are in one of the text modes. With ROM-BIOS, position to {0,0}. With ANSI.SYS, position to {1,0}. Use ROM-BIOS to fetch the current cursor coordinates. If {1,0} then ANSI.SYS is installed; otherwise not.

So you positon it away from {0,0}, then you read it. If you get back *anything* that doesn't match what you expect, either 1)you're not running ANSI or 2)you have a bug :-) -- ------ ross m. greenberg ihnp4!allegra!phri!sysdes!greenber [phri rarely makes a guest-account user a spokesperson.
