<code>'''COMMAND.COM'''</code> is the default [[command-line interpreter]] for [[MS-DOS]], [[Windows 95]], [[Windows 98]] and [[Windows Me]]. In the case of DOS, it is the default user interface as well. It has an additional role as the usual first program run after [[Booting|boot]] ([[init process]]). As a shell, COMMAND.COM has two distinct modes of operation: [[Read-eval-print loop|interactive mode]] and [[Batch processing|batch mode]]. Internal commands are commands stored directly inside the COMMAND.COM [[Binary file|binary]]; thus, they are always available, but can only be executed directly from the command interpreter.{{Citation needed|date=March 2024}}
