Creating a macro and applying a loop but it's failing

LuisMijares · Posted 01-08-2025 10:43 AM

Hello,

I have a block of code that is quite repetitive, as it processes similar tasks across multiple datasets. To streamline this, I’m trying to create a macro, medpar_analysis, to loop through the dataset medpar for the years 2019 to 2021.

However, when I run the macro, I encounter the following error:

ERROR 161-185: No matching DO/SELECT statement.

The error points to a specific line of code within the macro. Interestingly, when I run the same code for an individual dataset (e.g., medpar_2019), it compiles and executes without any issues. This leads me to believe the issue lies in how the macro handles loops or iterates over the datasets.

I’m unsure where the unmatched DO loop or SELECT statement might be causing the error. Could you help identify the problem and suggest a solution?

Not sure if you're still looking for a solution, but if so, I would suggest putting this code in a code block (using the little SAS icon in the formatting tools when you're submitting a question here) or in an actual text editor that allows block indentation and then making all the indentation correct - in particular, the do-end blocks:

if x>3 then do;
    if y>7 then do;
        * stuff ;
    end;
end;

This will really help reveal where you might be missing a DO -- the error message you're getting seems to indicate that you have a stray END somewhere. I looked through your code (I'm very familiar with MedPAR) and I don't see one -- there's the one that looks out of place, but it appears to be commented out - right above the first /* verifying */ - so it shouldn't be causing a problem.

A few suggestions for making your code less repetitive / more efficient:

-- inside the loop where you keep doing strip(dgns[i]) --- instead of this, first thing inside the loop, just do this:

dgns[i]=strip(dgns[i]);

...after that, you don't need strip anymore.

I'm not sure I understand the point of the indicator steps. Are you just trying to preserve the location in the array where you found the code of interest? If so, you can skip that entire thing and instead modify your main loop for a given condition like this:


do i=1 to dim(DGNS);
  if missing(dgns[i]) then leave;
  dgns[i]=strip(dgns[i]);  * i do not think this is even needed ;
  if dgns[i] in depression_codes then do;
    DEPRESSION_MEDPAR=1;
    depression_pos=i;  * save the location in the array where this occurred ;
    leave;
  end;
end;

Note the two LEAVE statements -- the first says, if we're reached the point in the array where we find a missing dgns, we can exit the loop - there is no need to check further. MedPAR does not have blanks followed by more codes. The second leave says, we've found the condition (depression) of interest -- set our flag DEPRESSION_MEDPAR to 1, store the position (i) as depression_pos, and leave (no need to keep checking unless for some reason you care if there is more than 1 depression code for the same visit - in general, this is not useful). If you do for whatever reason want to count all the positions where depression is present, then do this instead:

depression_count=0;
do i=1 to dim(DGNS);
  if missing(dgns[i]) then leave;
  dgns[i]=strip(dgns[i]);  * i do not think this is even needed ;
  if dgns[i] in depression_codes then do;
    DEPRESSION_MEDPAR=1;
    depression_count+1;  * keep track of the number of depression codes found ;
  end;
end;
depression_count_all=(depression_count>0);

Note the 2nd leave statement is now gone, so the loop will continue until it finds the first missing dgns.

Didn't we already figure this out on your first posting?

You have a statement comment in the code that was missing its semicolon. That turned one of the DO statements into part of the comment. Hence you ended up with an extra END statement.
