Subject:      what's wrong with adding %str(,), parmbuff
Content-Type: text/plain; charset="us-ascii"

Greetings!

The code below is supposed to print off two data sets sashelp.buy and
sashelp.air.
But it cannot run smoothly unless getting rid of the two occurrences of
%str(,).
Could you please explain to me what's wrong with adding those %str(,)?

Thank you very much.

%mend printz;

%printz(buy, air)
