Some old ms-dos demos refuse to run, I only get an “run time error 200”. Whats that?
It’s a crt unit init error, likely to happen with demos coded using old borland (turbo) pascal versions. There are several ways to fix it. Here are a few of the many web pages that explain the issue and offer help: – http://www.brain.uni-freiburg.de/~klaus/pascal/runerr200/ – http://www.merlyn.demon.co.uk/pas-r200.
