Symptom: A legacy MS-DOS program crashed while leaving the cryptic error message.
A runtime error 200 message usually occurs with old DOS applications written in Turbo and Borland Pascal. Turbo Pascal had a timing bug that would cause its complied programs to crash when they were operating on machines running at 200Mhz or faster. It is known as the CRT unit issue and can be fixed by applying a patch to the effected application. Otherwise you can run the application in DOSBox which can artificially slow down the speed of the emulated DOS session.
If you wish to patch the application we have created a guide to help you through it. Though this is only recommended for people experienced with DOS or the Windows command prompt.
