little book里的一段，有点儿问题。程序是如何知道在性别栏里找1，2， 在年龄栏里找年龄数字的？
PROC FORMAT; VALUE gender 1 = 'Male' 2 = 'Female'; VALUE agegroup 13 -< 20 = 'Teen' 20 -< 65 = 'Adult' 65 - HIGH = 'Senior';
详细见下面
Example Universe Cars is surveying its customers as to their preferences for car colors. They have information about the customer’s age, sex (coded as 1 for male and 2 for female), annual income, and preferred car color (yellow, gray, blue, or white). Here are the data: 19 1 14000 Y 45 1 65000 G 72 2 35000 B 31 1 44000 Y 58 2 83000 W The following program reads the data; creates formats for age, sex, and car color using the FORMAT procedure; then prints the data using the new formats: DATA carsurvey; INFILE 'c:MyRawDataCars.dat'; INPUT Age Sex Income Color $; PROC FORMAT; VALUE gender 1 = 'Male' 2 = 'Female'; VALUE agegroup 13 -< 20 = 'Teen' 20 -< 65 = 'Adult' 65 - HIGH = 'Senior'; VALUE $col 'W' = 'Moon White' 'B' = 'Sky Blue' 'Y' = 'Sunburst Yellow' 'G' = 'Rain Cloud Gray';

唉 sas感觉都快死了
很多都是r或者python

只是学来玩玩
它不需要知道啊 你只是创建了一个格式，还没使用。如果使用的时候性别不是1/2会报错的
谢谢，祝好。

: 错的
sas的所谓格式，是个很好的发明，功能很强大。别的语言好像没有。
嗯
Yes,Proc Format is one of the beautiful things in SAS, I love it. It is
quite unique, other analytic tools don't have the similar thing.

现在还在用SAS的 公司还多吗？ 好像在Indeed上搜SAS工作机会，好多都是migration away from SAS。。。
