Here's one example.  Neither Anthropic's Claude nor ChatGPT can give me a revision that works: /********** 05.01 Analyze Duads in Batches **********/ %macro analyze_duads_batches;   %do i = 1 %to &num_batches;     %let start_row = %eval((&i - 1) * 1000 + 1);     %let end_row = %eval(&i * 1000);     proc sql noprint;       select duad into :duads_batch separated by ' '       from SAS_1.all_duads       where row_num between &start_row and &end_row;     quit;     %put NOTE: Processing batch &i from row &start_row to &end_row;     %analyze_duads_batch(&duads_batch);   %end; %mend;    /********** 06.01 Analyze Each Duad **********/ %macro analyze_duads_batch(duads_batch);   %let num_duads = %sysfunc(countw(&duads_batch));   %do j = 1 %to &num_duads;     %let duad = %scan(&duads_batch, &j);     %let var1 = %scan(&duad, 1, '_');     %let var2 = %scan(&duad, 2, '_');     %put NOTE: Analyzing duad &duad with variables &var1 and &var2;     proc reg data=SAS_1.train_data outest=SAS_1.results_&duad (keep=_RSQ_ _P_);       model &response_var = &var1 &var2;     run;     /* Check for errors and log the message */     %if &syserr ne 0 %then %do;       %put ERROR: Regression analysis failed for duad &duad.;     %end;     %else %do;       %put NOTE: Successfully processed duad &duad.

"...only then try to turn that code into a macro. That will be a bazillion times easier than creating a macro from scratch."   Likely the LLMs go the macro route from scratch. LLM, "Piece of cake, boys..."     ... View more

The primary problem, so it seems, has to do with macros. The art of using macros is a bit tricky?   ... View more

"To generate code..." Actually, the question was, to review code.   And, the more specific question is whether ANY of the current LLMs have a better ability to do this, review SAS code. One can probably show any of them some SAS code, say, with a mistake or two.  So, how do they handle it?  Do any of them respond, for example, "you are missing a semicolon at this point".   Yes, no, maybe?  Things are what they are.     ...

The culprit appears to be "What failed: win32kbase_rs.sys."   SAS worked perfectly before this Windows 11 Beta change was made, and I, unfortunately, updated to it.   Crazy, the milli-instant I double click on Sas.exe, POW, the whole screen goes green.  Totally terminal.   ... View more

Thanks for stepping forward, old friend.  I tried your suggestion, but SAS still instantly crashes when I try to start it.   I'm using M7.  Perhaps M8 doesn't crash.  Who knows.   Wish there were an easy solution.   ... View more

@Ksharp   Yes, I know.  Mainland, would be my guess.  SAS with everything in Chinese just seemed even more overwhelming than SAS in English.  Like, OMG!!     ... View more

@Ksharp Noticed that your labels in the above graph are in Chinese. How about that.... ... View more
