Storing a value of each iteration of do loop

[jhabikaskumar26]

I want to create a macro variable suffix1 suffix2... Suffix12 variable such that
suffix1= 11 12 13
Suffix2= 21 22 23 so on
I tried using two do loop for it. But after each iteration new value get replaced with old one without storing it. Please do help me if anyone knows how I can code it in sas studio.

Please show your current attempt.

I have attached below a pdf which contains snapshot of code and log. In that we can observe that suffix12 resolves to 123 in last iteration but I want it should contains 121 122 123.

Here, I want macro variable suffix12= 121 122 123. Please do help me in modifying my existing code.

See this:

%macro data;
%do i=1 %to 12;
  %let suffix&i=;
  %do j=1 %to 3;
    %let suffix&i. = &&suffix&i. &i&j;
  %end;
  %put &&suffix&i;
%end;
%mend data;

%data
