Check out the man page for ksh. Under the section Parameters

Code:
       ?      The  exit  status of the last non-asynchronous command executed.
              If the last command was killed by a signal, $?  is  set  to  128
              plus the signal number.

In short, it holds the exit status of the command that was executed last.
