问题描述

我正在尝试完成以下任务.我已经尝试过使用数组和排序，但是似乎没有任何效果.任何帮助将不胜感激.

I'm trying to accomplish the following. I have tried using arrays and sorting but nothing appears to work.Any help would be appreciated.

Acct     Score1   Score2
9999       45       78
9999       58       65
8888       43       80
8888       43       90
8888       31       70

This is what I would like to end up with
Acct     Score1     Score2
9999       58         78
8888       43         90

因此，基本上，保持每个帐户的最高得分.

So basically, keep the highest score for each account.

推荐答案

只需使用PROC MEANS.

  class acct ;
  var score1 score2 ;
  output out=want max= ;
