Hi,

 

I have a variable that consists information about diagnosis (6496 different diagnosis). For each diagnosis i want to create a dummy variable and i used this code:

DATA b2;
  set b;
 
  ARRAY dummys {*} 3.  diag1_1 - diag1_6496;
 
  DO i=1 TO 6496;			      
    dummys(i) = 0;
  END;
  dummys( diag1  ) = 1;		
 
RUN;

However, I get this error message:

 

Array subscript out of range at line 2087 column 1.

 

Can anyone tel me what is wrong with code?

 

thank you

Obviously, the value of the DIAG1 variable is not always between 1 and 6496. Is it missing or 0 in some observations? What does the log say about the value of DIAG1 when the error occurs?

Thanks,

There is no 0 or missing values; however, I found what was wrong with code (my values were letters not numbers) and I made it work

I would question why you want to do this.  Just take a simple example of having two records:

DIAG

34

26

 

This is two datapoints of information.  If you transpose that into your structure, you would have 6496 datapoints of information.  This is just a simple example of where your intended data structure is very verbose in terms of storage, but you will also find your coding is far harder as well.
