what is the wrong with my macro code below?

Hi Forum,

Could you please help me to figure out what is the wrong with my macro code below , i have created macro variable at the end .

%macro outer_reconcil(dataname =%str() );
proc sort data = comment_&dataname;
by subject aespid;
run;
%mend outer_reconcil;

%outer_reconcil(dataname = %str(Event_not_rec));

still getting

15355 %outer_reconcil(dataname = %nrbquote(Event_not_rec));
MLOGIC(OUTER_RECONCIL): Beginning execution.
MLOGIC(OUTER_RECONCIL): Parameter DATANAME has value Event_not_rec
SYMBOLGEN: Macro variable DATANAME resolves to Event_not_rec
SYMBOLGEN: Some characters in the above value which were subject to macro quoting have been unquoted
            for printing.
NOTE: Line generated by the macro variable "DATANAME".

Why use %str() ? It makes them in different compile level .

HI Xia , Thanks for the Answare .

%str(Event_not_rec) is in a compile stage . comment_ is in another compile stage . when you put them together comment_%str(Event_not_rec) , SAS would compile them in the different stage . That is reason why you got ERROR .

To clarify something more . %str() %nrstr() %superq() ......... they are all macro variable mask function , they will add mask character around macro variable . For this example , you can take it as \bEvent_not_rec\b , \b is the mask character , therefore the real code generated in compile engine is comment_\bEvent_not_rec\b , so you get the ERROR message . if you don't put %str() around it , it will generate code comment_Event_not_rec , that is right code we need .

Because you quoted the macro string in the call it is confusing the parser. It sees two tokens instead of one.

Your macro can adjust for this by adding an %UNQUOTE().

proc sort data = %unquote(comment_&dataname) ;

by subject aespid;

run;

proc sort data = comment_%unquote(&dataname) ;

by subject aespid;

run;
