CODESEG          Define code segment                                Directive

  CODESEG [segname]                     ; Ideal or MASM mode
  .CODE [segname]                       ; MASM mode

    Begins or continues the module's code segment when used with the MODEL
    directive. For memory models whose code is FAR, you can follow the
    CODESEG directive with an optional segname that indicates the name of
    the segment (defaults to <modulename>_TEXT).

    Note that you can generate more than one code segment per module this
    way.
