SAS Macros to Search and Report Errors and Warnings from your SAS Logs

How many a times at work have you gone thru the logs looking for ERROR, WARNINGS, NOTES etc for more information about the generated problem?…I’ve been doing a lot like that lately for developing / debugging / lines of code for more information…I just wished I had a piece of code that would search and report me the location / line number and few more information about….luckily I found this macro in a SAS SUGI paper…here’s the link….www2.sas.com/proceedings/sugi25/25/po/25p219.pdf

Then I had to customize it a little more to make the macro browse thru a folder of log files with a common runtime so that I can get all the errors into one report file…

Here’s an example and the full code below….

I intentionally induced couple of errors highlighted in RED font locations in these datasteps below….

%let LogLoc=C:\SASDATA;

%let cyle_runtime=10OCT2010102001;

proc printto log=“&LogLoc.\example1_&cyle_runtime..log”; run;

DATA example1;

INPUT ID $ 1 SBP 2–4 DBP 5–7 GENDER $ 8 AGE 9–10 WT 11–13;

DATALINES;

1120 80M15115

2130 70F25180

3140100M89170

4120 80F30150

5125 80F20110

;

RUN;

PROC MENS;

RUN;

proc printto; run;

proc printto log=“&LogLoc.\example2_&cyle_runtime..log”; run;

DATA CDS2;

run;

ODS RTF;

PROC FREQ DATA=CDS ORDER=FREQ; WEIGHT NUMBER;

TITLE3 ‘READ IN SUMMARIZED DATA’;

TABLES CATEGORY;

RUN;

proc printto; run;

This code produces 2 log files at C:\SASDATA\ with timestamp on them…

Now running my SAS Macro %ReportErrorWarnings with the right parameters would result in a Error file at the same location…

%ReportErrorsWarnings(searchstr,searchloc,searchfiles,outfile,lines2display);

The macro from the SUGI paper was good…it created an arrow against the error / filename and linenumber…I customized the macro to browse thru a folder / location of logs etc… I agree it isn’t pretty but it works for me….This error file gives me the exact location (for eg line 20 in example 1 file and 2 lines above and below….). The number of lines to display above and below is again customizable though as the last parameter…

Similarly one can search for “ERROR:”,”WARNING:”, “NOTE:”,”not resolved”, “uninitialized”, “invalid data”, “_ERROR_=1”, “missing values”, “lock held by” etc…any other usual errors that you might want to track.

%ReportErrorsWarnings(searchstr,searchloc,searchfiles,outfile,lines2display);

Here’s the full code…with the repeatition of the above code again…for context…

You can get it from here as well…
