How to eliminate data error notes from the SAS log

Here's a simple datastep.  Notice the missing dollar sign to indicate the variable GENDER (M, F) is a character variable.

data class; infile 'c:\temp\class.csv' dsd; input name $ gender age; run;

We've all seen those ugly data error notes in the SAS log!

562 data class; 563 infile 'c:\temp\class.csv' dsd; 564 input name $ gender age; 565 run;   NOTE: The infile 'c:\temp\class.csv' is: Filename=c:\temp\class.csv, RECFM=V,LRECL=32767,File Size (bytes)=236, Last Modified=03Dec2014:12:46:20, Create Time=03Dec2014:12:46:20   NOTE: Invalid data for gender in line 1 8-8. RULE: ----+----1----+----2----+----3----+----4----+----5 1 Alfred,M,14 11 name=Alfred gender=. age=14 _ERROR_=1 _N_=1 NOTE: Invalid data for gender in line 2 7-7. 2 Alice,F,13 10 name=Alice gender=. age=13 _ERROR_=1 _N_=2 NOTE: Invalid data for gender in line 3 9-9. 3 Barbara,F,13 12 name=Barbara gender=. age=13 _ERROR_=1 _N_=3 NOTE: Invalid data for gender in line 4 7-7. 4 Carol,F,14 10 name=Carol gender=. age=14 _ERROR_=1 _N_=4 NOTE: Invalid data for gender in line 5 7-7. 5 Henry,M,14 10 name=Henry gender=. age=14 _ERROR_=1 _N_=5 NOTE: Invalid data for gender in line 6 7-7. 6 James,M,12 10 name=James gender=. age=12 _ERROR_=1 _N_=6 NOTE: Invalid data for gender in line 7 6-6. 7 Jane,F,12 9 name=Jane gender=. age=12 _ERROR_=1 _N_=7 ... NOTE: 19 records were read from the infile 'c:\temp\class.csv'. The minimum record length was 9. The maximum record length was 12. NOTE: The data set WORK.CLASS has 19 observations and 3 variables. NOTE: DATA statement used (Total process time): real time 0.04 seconds cpu time 0.04 seconds

Suppressing the data error notes in the SAS log is easy!

options errors=0;

But the above approach only masks the bad news.  That is why the student wanted to write these notes to a separate file.  Here's how!

data class; infile 'c:\temp\class.csv' dsd; input name $ gender age; if _error_=1 then do; file 'c:\temp\MyInvalidDataNotes.txt'; put 'NOTE: Invalid data in line ' _N_; put _infile_; put _all_; put; end; run;

In SAS, there's always a way!
