【灌水】ug API 中的圈套！！

     UF_SETUP_generate_clsf   这个函数的说明文字如下：
  
     This function generates the CLSF for all the operations contained in
the specified group of the specified setup. It will use the instructions
(i.e., the Definition File and Event Handler) specified by 'clsf_name'. It
will write the generated CLSF to a file with name 'output_filename'. If
'output_filename' exists it will be erased before writing new data to it.
See the Note in the File Description regarding the relationship between the
'clsf_name' and the CAM resource files.
  
如上红色的字所示的意思为：输出的文件将覆盖已存在的同名文件。
但是，在使用中发现，它并不是覆盖而是追加！！
  结果使我加工的零件完全报废了！真是苦啊～～～
