Can we eliminate the errors in the auto generated code?

[Tom]

Every time I submit code in SAS/Studio I get this annoying note (error) in the log.

 INFO: Character variables have defaulted to a length of 200 at the places given by: (Line):(Column). Truncation can result.
       40:1     RC

I was able to track it down to this data step that SAS/Studio is prefixing to my code.

 37         DATA _NULL_;
 38         CALL SYMPUT("GRAPHINIT","");
 39         CALL SYMPUT("GRAPHTERM","");
 40         RC=TSLVL('SASXGOPT','N');
 41         _ERROR_=0;
 42         IF (RC^=' ') THEN DO;
 43         CALL SYMPUT("GRAPHINIT","GOPTIONS RESET=ALL GSFNAME=_GSFNAME;");
 44         CALL SYMPUT("GRAPHTERM","GOPTIONS NOACCESSIBLE;");
 45         END;
 46         RUN;
 
 INFO: Character variables have defaulted to a length of 200 at the places given by: (Line):(Column). Truncation can result.
       40:1     RC

Can we please fix that so it does not generate that message? 

Why is it even making the RC variable?  It is not used anywhere.

Just change to generate code like this instead.

DATA _NULL_;
  CALL SYMPUT("GRAPHINIT","");
  CALL SYMPUT("GRAPHTERM","");
  _ERROR_=0;
  IF (TSLVL('SASXGOPT','N')^=' ') THEN DO;
    CALL SYMPUTX("GRAPHINIT","GOPTIONS RESET=ALL GSFNAME=_GSFNAME;");
    CALL SYMPUTX("GRAPHTERM","GOPTIONS NOACCESSIBLE;");
  END;
RUN;

I'm second to that idea

B-)

@Tom ,

Did you set MSGLEVEL=i? If yes, that setting generates additional notes in the SAS log.

I have no idea whether I set it or not. Or whether SAS/Studio did either.

But it doesn't change the fact that the code should be fixed.  It is just sloppy coding to create character variables without a way for the data step to know what length it should use.  Which is why SAS is issuing that line in the log.

Thanks for your response. What version of SAS is it? I need that information to open a feature request.
