calling convention
     
         The arrangement of {arguments} for a procedure
        or function call.  Different programming languages may require
        arguments to be pushed onto a {stack} or entered in
        {registers} in left-to-right or right-to left order, and
        either the caller or the callee can be responsible for
        removing the arguments.  The calling convention also
        determines if a variable number of arguments is allowed.
