DOS Error Code Descriptions

DOS was designed to run on computers with far less processing power than is currently available today. To keep memory to a minimum, errors were reported by displaying an error number rather than a descriptive message. The following is a list of what the error messages would have been if space for a translation table had been available. Error numbers are shown in bold.

I don't know what error codes 14 and 81 were for. Those error codes which translate to the same error message in the above list are presumably triggered by different problems. I don't have any more detailed explanation of what some of these error messages actually mean and what the real causes of the errors are but presumably most of the ones that are not obvious would normally only show up during program testing of a newly written program.
