宏命令应用

我用范成建《虚拟样机软件MSC.ADAMS应用与提高》中关于用宏命令建立齿轮的应用，
出现三个同样类型的错误：
ERROR:   ---------------------------------------------------------------------
ERROR:   Error detected on line number 123, character 6 of poly_gear.cmd.
ERROR:   No Reference_Frame was found because 'close' does not exist beneath '.gear_5'.
ERROR:   The command was not executed.
ERROR:   &> close=yes relative_to=.gear_5.PART_2.MARKER_1

ERROR:   ---------------------------------------------------------------------

请宏高手指点！
涉及到的宏命令只有三行（红字部分）：
file text write&
     format_for_output="close=yes relative_to=%s"&
     values_for_output=($center_marker) newline=yes

file text close

variable delete variable=$_self.inc
variable delete variable=$_self.a_inc,$_self.num_teeth,&
     $_self.out_rad,$_self.in_rad,$_self.out_rad2

file command read file_name=poly_gear

geometry create shape extrusion extrusion_name=&
$ref_part_name.$gear_name profile_curve=tmp_poly&
reference_maker=$center_maker length_along_z_axis=$thickness
geometry delete geometry_name=tmp_poly
