Create Macro Variable from dataset column and bound by quotes

Hi,

I managed to create a macro variable that read-in from a dataset column.  However, I would like to bound those individual "cell" by quotations.

The code I used to is as follow:

*** creating dataset TABLELIST with all dataset with name begin with "_" in CC library ;

    DATA WORK.TABLELIST (KEEP=MEMNAME);

      SET SASHELP.VMEMBER

      (WHERE = (UPCASE(LIBNAME)= "CC" AND UPCASE(MEMNAME) =: '_'));

      RUN;

    PROC SQL NOPRINT;

      SELECT MEMNAME

        INTO :TABLES SEPARATED BY " "

      FROM WORK.TABLELIST;

      QUIT;RUN;

What I want to achieve is &tables. macro variable to be '_A' '_B' '_C' etc.

Now my code only managed to make &tables resolved as _A _B _C etc.

Thanks,

Jack

Double quotes are easier since you can use the QUOTE() function.  Just change MEMNAME to QUOTE(trim(MEMNAME)) in your SELECT statement.

To quote with single quotes you could use cats("'",MEMNAME,"'") instead.

Could I ask what you use the &TABLES. macro for later on.  Am just thinking if you have the SQL already you may be able to use that as a sub-query rather than assigning it to a macro variable.
