Hello,

I have a question about the macros.
Indeed in this simple example, I want to create a multitude of graphics.
Problem is that I have to write each time %er ( , ).

How to write that once % er? But that all graphics are produced.

With% let? %let p= a e r t y; ?

Thanks for your help

Data toto;
input a z e r t y;
cards;
1 2 3 4 5 77
6 45 4 8 7 99
4 5 6 8 7 22
1 2 5 4 7 88
;
run;

%macro er (x,y);
proc sgplot data=toto;
scatter x=&x. y=&y./ datalabel;
run;
%mend;
%er (a,z);
%er (a,e);
%er (a,r);
%er (a,t);
%er (a,y);
%er (z,a);
%er (z,e);
%er (z,r);
%er (z,t);
%er (z,y);
%er (e,a);
%er (e,z);
%er (e,r);
%er (e,t);
%er (e,y);

...

.........It is too long 😕

Well first off, you would be better off modelling your toto dataset in such a way that you don't have to do this, i.e. just two columns x and y.

But you can do something like:

Data toto;
input a z e r t y;
cards;
1 2 3 4 5 77
6 45 4 8 7 99
4 5 6 8 7 22
1 2 5 4 7 88
;
run;
%macro er (x,y);
 %put x=&x. y=&y.;
%mend;

data _null_; 
 array tmp {*} a z e r t y;
 do i=1 to 6;
   do j= i+1 to 6;
     call execute(cats('%er (x=',vname(tmp{i}),',y=',vname(tmp{j}),');'));
   end;
 end;
run;
