how to excute sas macro iteratively in another macro? - loops

Question

i would like to get result of brand_channel macro.
macro is not working on i=2,3,4 in %do-loop statement.
How can I execute doing_scoring macro iteratively?
thanks!
%doing_scoring;

%mend doing_scoring;
%macro brand_channel;
proc sql noprint;
create table oneb_onec as
select unique x1, x2
from mydata_all;
quit;
data seq_oneb_onec;
set oneb_onec;
seqno = _N_;
run;
%let num=4;
%do i=1 %to #
%put doing number is &i;
%put end doing number is #
proc sql noprint;
create table onebc_table&i as
select a.*
from mydata_all a, seq_oneb_onec b
where b.seqno = &i
and b.x1 = a.x1
and b.x2 = a.x2;
quit;
%doing_scoring(mydata=onebc_table&i, setnumber = &i);
%end;
%mend brand_channel;
%brand_channel;

Answer 1

Your code is fine, except for the initial line (declaration of doing_scoring), but that's likely transcription error I suppose.
Below I have a functional test version.
However, I have a better way to do the same thing. Fundamentally, macro driven iteration is a bad idea; there is a better way to do almost every task you might want to attempt.
In this case, you can call the doing_scoring calls directly from the seq_ dataset, and either move the creation of the sub-dataset to the macro (should be easy) or, perhaps better, keep the dataset in one piece.
First the better way: call execute. (Or, you can create the macro calls in SQL using select into.)
proc sort data=sashelp.class out=class;
by age sex;
run;
%macro doing_scoring(data=,age=,sex=,setnumber=);
data mydata;
set class;
where age=&age. and sex="&sex.";
run;
*whatever else you are doing;
%mend doing_scoring;
data _null_;
set class;
by age sex;
if first.sex then seqno+1;
callstr=cats('%doing_scoring(data=class,age=',age,',sex=',sex,',setnumber=',seqno,')');
call execute(callstr);
run;
Now, the original way with same test data.
%macro doing_scoring(mydata=,setnumber=);
%put doing_scoring &mydata. &setnumber.;
%mend doing_scoring;
%macro brand_channel;
proc sql noprint;
create table oneb_onec as
select distinct age,sex
from sashelp.class;
quit;
data seq_oneb_onec;
set oneb_onec;
seqno = _N_;
run;
%let num=4;
%do i=1 %to #
%put -------------------;
%put doing number is &i;
%put end doing number is #
proc sql noprint;
create table onebc_table&i as
select a.*
from sashelp.class a, seq_oneb_onec b
where b.seqno = &i
and b.age = a.age
and b.sex = a.sex;
quit;
%doing_scoring(mydata=onebc_table&i, setnumber = &i);
%put -------------------;
%end;
%mend brand_channel;
%brand_channel;
