发帖数: 12276 | 1 有个DATASET,里面的有些MISSING被输入了99，88，77。如何把99，88，77变成MISSING.
多谢！！ | c******j
发帖数: 270 | 2 if aaa in (99,88,77) then aaa=.; | z**********i
发帖数: 12276 | 3 Because a lot of variables in the dataset, I probably want to change all 99,
88,77 to ., but not 1988 or 1999 .
Thanks.

发帖数: 12276 | 5 I didnot try that. It looks like only change 77,88,99 for variable aaa.
I want to change all the 77,88,99 in the dataset, but not 1977,1988,1999.
Thanks.

发帖数: 3176 | 7 Do you mean that 1977 was coded as '77'? If so, you'd need to identify and
single out these year variables to be not included in the recoding.

发帖数: 9065 | 8 具体问题具体分析。楼主应该根据在什么情况下发生输入错误的现象，找出相应的解决
。一个通用的Code往往会有问题的。 | z**********i
发帖数: 12276 | 9 实际上，没有在dataset 里没有1977，我的意思是限定到77，88，99，不要把里面包含
这些数字的变了。
多谢回复！
