新手学习ADAMS宏命令遇到的问题

我按照书上例子做复制移动圆柱体的题目，编写的程序如下，完全是照书写的
!USER_ENTERED_COMMAND part replicate single
!HELP_STRING This command copies a part and offsets it a prescribe
!$marker_to_project_along:T=marker:C=1
!$offset_distance:T=real=50
!$which_axis:T=list(x,y,z)=Z
!
var cre var=$_self.tmp_mod object=(eval(DB_DEFAULT(.System_Defaults,"model")))
var cre var=$_self.tmp_name string=(eval(UNIQUE_LOCAL_NAME($_self.tmp_mod,($marker_to_project_along.parent.name))))
!
part copy&
     part_name=($marker_to_project_along.parent)&
     new_part_name=($_self.tmp_name)&
!
if cond=("$which_axis"=="x")
move object part_name=($_self.tmp_name)&
   c1=$offset_distance c2=0 c3=0&
   csmarker_name=$marker_to_project_along&
   incremental=yes
!
elseif cond=("$which_axis"=="y")
move object part_name=($_self.tmp_name)&
    c1=0 c2=$offset_distance c3=0
    csmarker_name=$marker_to_project_along&
    incremental=yes
!elseif cond=("$which_axis"=="z")
move object part_name=($_self.tmp_name)&
    c1=0 c2=0 c3=$offset_distance&
    csmarker_name=$marker_to_project_along&
    incremental=yes
end !if
var del var=$_self.*

可是执行命令时总是提示错误，求高手帮帮忙，谢谢：
