如何将ugnx2开发的程序用到ugnx3

各位大哥：
     请教一个问题，我在nx2中开发的程序如何在nx3当中用呢？请个位高手指点迷津，谢谢了？
LICENSE.GRS.dem文件如下：

$$ SUBROUTINE:  LICENSE.GRS
$$                           
$$ ABSTRACT:
$$   This program is used to check license for given id_number,
$$   and called by ***m.grs programs.
$$
$$ KEYWORDS:
$$   license_str   -- id_number read directly from  operation system  
$$   id_str           -- id_number specified  the users
$$
$$ RELEASE HISTORY
$$        95.10.28 INITIAL SUBMISSION

PROC/
  STRING/str(70),license_str(70),id_str(10,70)
$$
$$   get ID_number imformation by UNIX command <LANSCAN> ,and write it to  
$$   a file named as 'sd_part_license_name'. Then read it to a string varible
$$   STR from the file, and extract ID_number from STR  into LICENSE_STR.
$$  
$$   XSPAWN/'/bin/ksh','-c','/etc/lanscan  > sd_part_license_name'
$$   next line is for SGI platform
$$XSPAWN/'/bin/ksh','-c','/etc/sysinfo > sd_part_license_name'

$$ ID_STR varible can be changed accordion to actual workstation ID_number

GRIP不会。
软件传统是向下兼容，在NX2如何用，NX3应该差不多吧
