mediate step of extracting an op code of said
macroinstruction. Gries teaches on page 245 translating a
source code into an internal form which is easier to handle
mechanically. Gries further discloses that in most internal
forms, operators appear essentially in the order in which they
are to be executed. We fail to find from this disclosure that
Gries teaches or suggests directly encoding a literal source
code macroinstruction into a corresponding sub- routine
address. Turning to page 248 of Gries, we fail to find that
Gries discloses or suggests directly encoding a literal source
code macroinstruction into a corresponding subroutine address
as well. Gries' algorithm for executing an arithmetic
expression into Polish notation is not the same as a
subroutine address and is not the same as a macroinstruction.
Appellant argues on pages 7 and 8 of the brief that
neither Gries nor Horowitz, singly or in combination, teaches
or motivates one of ordinary skill in the art to create an
execution
