With regard to the dining philophers problem, some of the Ada solutions I have access to presume a VT100 style of terminal. This is really a windows95/98 question about using Ada; but how do I define a DOS/ whatever window so that I can run such a program and have it do the right thing. I know that I can telnet to a unix box, and have a terminal window, but what I'm looking for is a vt100-style window on my home & demo PC. Thanks, ..Paul
