exit command status

Exit command status returns 0, if command is successful and non-zero if command is
not running successfully. If a command is run on cmd prompt and if that command is
running successfully, I will get the output. So when do I get 0 instead of output
on success ? If command does noy run successfully, I get error message. When do I
get non-zero value instead of error message ?

Its two different things. You're asking about a exit (status) code. The value is
returned to the calling program. It is not output to the screen. If you execute
the command from a batch file then the batch file will receive the exit code so that
you can do with it as you please. Its for programmers.

When a program calls a subroutine, if that subroutine runs successfully then code
"0" is returned with the message, right ? If subrioutine does not run successfully,
then non-zero value is returned with the error message. Calling program desplays
the message but does not display the code, right ?

Exactly. The calling program can interpret the error code as necessary. If that
means displaying an "english" error message, then that is what happens.
