Last Iteration of do/end not resolving

I have this code:

options symbolgen mprint mlogic;
%let cnt_id_groups=5;
%let cnt_Id_value_groups=8;
%macro dummy;
%do i = 1 %to &cnt_id_groups.;
	%do j=1 %to &cnt_Id_value_groups.;
		%let value_&i._&j=;
	%end;
%end;
%mend dummy;
%dummy;
%PUT VALUE_4_4=&VALUE_4_4;
%PUT VALUE_5_8=&VALUE_5_8;

Why would i not get the value for macro -- value_5_8?
what should i do?

Here is the log:

28         options symbolgen mprint mlogic;
29         %let cnt_id_groups=5;
30         %let cnt_Id_value_groups=8;
31         %macro dummy;
32         %do i = 1 %to &cnt_id_groups.;
33         	%do j=1 %to &cnt_Id_value_groups.;
34         		%let value_&i._&j=;
35         	%end;
36         %end;

Why would i not the value for macro -- value_5_8?

This macro variable was created inside the macro and is not defined outside the macro. You could include a %GLOBAL command inside the macro.

 %global value_5_8;

By the way, this looks like a overly complicated use of the macro language, and I bet there a much simpler ways to go. Please describe why you doing this, in words, at a high level so that your boss's boss would understand the project, and please tell us in words what would you do with these macro variables after they are created.

For one thing you create a pile of macro variables and do not assign any values to them.

One suspects that the macro variable Value_4_4 was created earlier, with different code, in such a manner that it appears in the GLOBAL table. Since the approach you are using with %dummy does not place the variable into the global table it is local and stops existing when the macro ends. Since we had a similar question from you earlier you might want to be aware that CALL SYMPUTX by default places everything into the global macro variable table.

Test whether other variables were earlier placed in the global table with:

%put _global_;

Depending on what you have done prior you might examine &value_1_8, &value_2_8 etc. I suspect you may find all of them undefined as well.

FWIW, I get the same Unresolved note about Value_4_4 (because I haven't run any code that placed it into the global table.

You need to populate your macro variables AND you need to define it as %global if you want to use it outside of your macro.

Hope below will give you some guidance.

%let cnt_id_groups=5;
%let cnt_Id_value_groups=9;
%macro dummy;
  %global value_&cnt_id_groups._&cnt_Id_value_groups;
  %do i = 1 %to &cnt_id_groups.;
  	%do j=1 %to &cnt_Id_value_groups.;
  		%let value_&i._&j=%eval(&i * &j);
  	%end;
  %end;
  %put last_iter_macro var name:  value_&cnt_id_groups._&cnt_Id_value_groups;
  %put last_iter_macro var value: &&value_&cnt_id_groups._&cnt_Id_value_groups;
%mend dummy;
%dummy;

%put value_&cnt_id_groups._&cnt_Id_value_groups: &&value_&cnt_id_groups._&cnt_Id_value_groups;
