macro to create a shell for multiple treatment groups

[jenim514]

Hi all,  I need a little help with a macro.  I basically need the below code to repeat exactly for the 9 treatment groups to create a dummy shell.  I then the output from each treatment group to 'stack' as to create a large shell  with 31 observations output from each treatment group.  The away this is currently written, I am only getting output from group 'T" (the last entered group).

Help is appreciated!

%macro dummy (tx);
data dummy ;
do tx="&tx";
	do ord=11 to 41;
		if ord=11 then do;
		do sord=1 to 2 ;
		output;
		end;
		end;
	if ord=21 then do;
		do sord=1 to 8;
		output;
		end;
		end;

	if ord=31 then do;
		do sord=1 to 12;
		output;
		end;
		end;
	if ord=41 then do;
		do sord=1 to 9;
		output;
		end;
		end;
	end;
end;
run;
%mend dummy;
%dummy (A);
%dummy (B);
%dummy (C);
%dummy (D);
%dummy (E);
%dummy (F);
%dummy (G);
%dummy (H);
%dummy(T);

To get your program to work, get rid of the macro language.  Take this statement:

do tx="&tx";

Change it to:

do tx = 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'T';

Then you can get rid of everything that is macro-related and be left with a DATA step.

As it stands now, each time you call the macro, you replace the data set DUMMY.  That seems like the wrong thing to do.
