data base1; set lib.base1; run; proc summary data=base1 nway missing; class prd; var gp; run;
My prd is a set of date. I am required to extract the first 4 digits of it. For example, 202012, and I only need 2020.
Is there any way to extract it? Thank you.
Depends on the type of prd:
Let say it's a string. How would I convert? Can you show me the line of code? Thank you.
data base1;
set lib.base1;
prd2=substrn(prd,1,4);
run;
