Indirect command file

          At any point when entering a command line, Turbo Assembler lets
          you specify an indirect command file by preceding its name with
          an "at" sign (@). For example,

                tasm /dTEST @myproj.ta

          causes the contents of the file MYPROJ.TA to become part of the
          command line, exactly as if you had typed in its contents
          directly. You can split the contents of an indirect file on as
          many lines in the file as you want.

          You can use more than one indirect file, and you can mix indirect
          files with normal command line arguments.
