Macro List

[Katie]

I have the following code: 

%MACRO DATAPREP(DATA);
%DO i = 1 %TO 1;

PROC SORT DATA = FIMR.Sleep_Logistic;
BY Case_ID__;
RUN;

PROC SORT DATA = FIMR.%SCAN(&DATA,&i);
BY Case_Number;
RUN;

DATA %SCAN(&DATA,&i);
MERGE FIMR.Sleep_Logistic (IN = A KEEP = Case_ID__ RENAME = (Case_ID__ = Case_Number)) FIMR.%SCAN(&DATA,&i) (IN = B);
BY Case_Number;
IF A and B;
RUN;

PROC CONTENTS DATA = %SCAN(&DATA,&i) NOPRINT OUT = Contents_%SCAN(&DATA,&i);
RUN;

DATA Contents_%SCAN(&DATA,&i);
SET Contents_%SCAN(&DATA,&i);
IF Length NE 1 THEN DELETE;
IF Name = 'Fetal__F__Infant__I_' THEN DELETE;
KEEP Name VarNum;
RUN;

PROC SQL;
SELECT DISTINCT Name
INTO :List_%SCAN(&DATA,&i) SEPARATED BY ' '
FROM Contents_%SCAN(&DATA,&i)
ORDER BY VarNum;
QUIT;

%END;

%MEND;

%DATAPREP(DATA = Environment);

When I then type the following: 

%PUT &List_Environment; 

I get an error that states that the symbolic reference List_Environment is not resolved.  Please HELP.

Hi @Katie,

Please add the following statement to your macro (e.g. before the PROC SQL step).

%GLOBAL List_%SCAN(&DATA,&i);

Edit: %GLOBAL List_Environment; would work only for this specific macro variable, but in your case the name is dynamic.
