使用 PROC SCORE 更改数据集中的值，使用 SAS

Question

I'm New to SAS Please can one help me how to change the value of data set using PROC SCORE. I have two data set as shown below image how to append the label value from data set 2 to set 1.

If gender is 1 We should append the value as M from the set 2

Answer 1

SAS uses formats as the way to display values in human friendly ways. Looks like you want to convert your second table into a format definition so that you can attach that format to the GENDER variable in your first dataset.

From the description it sounds like you want to generate a custom format like this:

 proc format ;
   value gender 1='M' 0='F' other='O' ;
 run;

You could then use a FORMAT statement, inside your Proc SCORE step, to associate the custom format to your GENDER variable.

 format gender gender. ;

It is possible to build a format from a dataset, but you have not described any way to match the values of 0 and 1 in the first dataset to the values M or F in the second dataset. What was the logic for deciding that 1 should be mapped to M? Is it because M is first in the table? Is it because F comes before M in the alphabet and 0 comes before 1 in numeric ordering?
