The README for 2.0 contains an interesting apology to OEMs: > The user manual contains some significant errors. Most of these are due to last minute changes to achieve a greater degree of compatibility with IBM's implementation of MS-DOS (PC DOS). This includes the use of "\" instead of "/" as the path separator, and "/" instead of "-" as the switch character. For transporting of batch files across machines, Microsoft encourages the use of "\" and "/" respectively in the U.S. market. (See DOSPATCH.TXT for how you can overide this. The user guide explains how the end-user can override this in CONFIG.SYS). Both the printer echo keys and insert mode keys have now been made to toggle. The default prompt (this may also be changed by the user with the PROMPT command) has been changed from "A:" to "A>". We apologize for any inconveniences these changes may have caused your technical publications staff. So MS-DOS almost had Unix-style file separators and argument switches!
