Creating a column with IF procedure

[MerAgSo]

Hi, 

I'm new to SAS and I'm not sure what I'm doing wrong with my code. 

I have a big data set and I'm trying to create a new column from existing variables given that ANY of them is 1. 

Here is my code: 

data AVG1; 

set WORK.AVG1; 

       IF LPLAQUE=1 OR RPLAQUE=1 OR PLAQUE=1 OR PLAQUE1=1 

       THEN TPLAQUE=1; 

      ELSE IF LPLAQUE=0 OR RPLAQUE=0 OR PLAQUE=0 OR PLAQUE1=0

     THEN TPLAQUE=0; 

RUN; 

SAS doesn't come up with an error during the log, but on the output the table has no data. 

As I said, I am very new to SAS so I may be missing something very obvious. 

Thanks.

Well, you likely destroyed your original data so you'll first need to recreate avg1.

After you do that, please run the code (below) and post your log and explain what isn't working.

data AVG2; 
set WORK.AVG1; 
       IF LPLAQUE=1 OR RPLAQUE=1 OR PLAQUE=1 OR PLAQUE1=1 
       THEN TPLAQUE=1; 
      ELSE IF LPLAQUE=0 OR RPLAQUE=0 OR PLAQUE=0 OR PLAQUE1=0
     THEN TPLAQUE=0; 
RUN;
