dbDOS is software developed by dBase for Windows computers with Intel processors. dbDOS allows Intel-based PCs to run DOS Applications, such as dBASE III, dBASE IV (Version 1, 2, 3), and dBASE V for DOS in an emulated DOS environment. It is an environment configured specifically to allow the various versions of dBASE for DOS to run without any ...
The share MS-DOS subsystem command performs functions that are now inherent to Microsoft Windows. It is available to preserve compatibility with existing files, but has no effect at the command line because the functionality is automatic. The 16-bit MS-DOS subsystem commands are not available on 64-bit editions of Windows. [11]
