How do you call an external function or program that is written in different programming language?
It doesn't matter what language the external program or function was written in since all executables must be converted to machine code. To execute an external function, that function must reside in a library to which your program is linked and you must know the prototype of the function you intend to call. This is usually found in the library header file which can simply be included in your program. You can then call the external function just as you would an internal function. To execute a specific function in another program, however, you must use the command line interface for that program.

INTERNAL COMMANDSThese are those commands which are contained in command.com files of MS-DOS.These are those functions that are built into the command interpreter.There is no need of any external file in computer to read internal MS-DOS command.These commands can be used as long as DOS is running on the system.Internal commands do not vary from system to system.These are ver, time, del, md, cd, copy con, cls, date, vol, ren, copy etc.EXTERNAL COMMANDSThese are those commands which are not in-built in MS-DOS.External commands are those which are not included in the interpreter.There is a need of an internal file in the computer to read external MS-DOS command.External command may vary from system to system.

Why can a folder not be created with the name con?
In the older version of Windows, which was DOS, a few words were reserved names to address a piece of hardware. You can't even rename a folder as "prn", "aux" and many others. This is because they all stand for output devices. "con" stand for 'console', "prn" stands for 'printer' and "aux" stands for 'auxillary'. Thus, you can't use these folder names if you are using dos because it will cause an error. Even if you open command prompt and type "con" without quotes and press enter, it will show:- "' ' is not recognized as an internal or external command, operable program or batch file." It will not even display the word "con".
