下面形式的数据怎样放入SAS数据集

shiyiming

有以下形式的文本格式数据：
202.118.83.11 - - [05/Oct/2003:00:15:28 -0700] "GET /robots.txt HTTP/1.0" 404 276
202.118.83.11 - - [05/Oct/2003:00:15:30 -0700] "GET /nmc/images/net.gif HTTP/1.0" 200 72732
202.118.83.238 - - [05/Oct/2003:00:15:35 -0700] "GET /index.html    HTTP/1.0" 200 2220
202.118.83.238 - - [05/Oct/2003:00:15:35 -0700] "GET /index.html    HTTP/1.0" 200 2220
现在要取IP地址，时间（不包括[ ]），网页地址，如/robots.txt和倒数第二个数字，并放入sas数据集。应该怎样编码？ 谢谢您的浏览和解答！
