set a table with multiple table using do loop

[D_ANALYST]

Hello~

I'm quite new to the SAS platform.

I'm trying to make a one table with multiple table using do loop. 

There are two factors increasing until 10.

Here is the example.

Thank you for your help.

DATA OSUMF;
SET OSUM1F_1 OSUM1F_2 OSUM1F_3 OSUM1F_4 OSUM1F_5 OSUM1F_6 OSUM1F_7 OSUM1F_8 OSUM1F_9 OSUM1F_10
OSUM2F_2 OSUM2F_3 OSUM2F_4 OSUM2F_5 OSUM2F_6 OSUM2F_7 OSUM2F_8 OSUM2F_9 OSUM2F_10
OSUM3F_3 OSUM3F_4 OSUM3F_5 OSUM3F_6 OSUM3F_7 OSUM3F_8 OSUM3F_9 OSUM3F_10
OSUM4F_4 OSUM4F_5 OSUM4F_6 OSUM4F_7 OSUM4F_8 OSUM4F_9 OSUM4F_10

Why not just use a wildcard suffix?

data all;
  set OSUM: ;
run;

Are there other datasets that start with those characters that you DONT want to include?  If se why not? Where did they come from.

[D_ANALYST]

I didn't know about wildcard suffix.
It can be one of the solution.
I also want to know in case there are other datasets that start with characters that I don't want to include.
In case when there OSUM1F_1 ~ OSUM25F_25.
And I just want to use from OSUM1F_1 to OSUM10F_10
Then I can't use wildcard suffix.
What can I do for that case??

[D_ANALYST]

For example, there are two data table I want to make, OSUMC and OSUMD.
OSUMC makes with OSUM1C_1, OSUM1C_2, ... , OSUM10C_10
and OSUMD makes with OSUM1D_1, OSUM1D_2, ... , OSUM10D_10
In this case, it's hard to use wildcard suffix.
Both starts with "OSUM"
then what should I do?

There is an intermediate solution, as opposed to a DO loop (which would require macro coding, or programming for a CALL EXECUTE statement:

data osumf;
  set osum1f_1-osum1f_10   osum2f_2-osum2f_10   osum3f_3-osum3f_10
      osum4f_4-osum4f_10   osum5f_5-osum5f_10   osum6f_6-osum6f_10
      osum7f_7-osum7f_10   osum8f_8-osum8f_10   osum9f_9-osum9f_10
      osum10f_10;

Here is a semi-macro approach:

filename setstmt temp ;
data _null_;
  file setstmt;
  length txt $200;
  do x=1 to 10; 
    txt=catx(' ',txt,cats('osum',x,'F_',x,'-osum',x,'F_10'));
  end;
  put 'set ' txt ';' ;
run;
data _null_;
  %include setstmt /source2;
run;

[Kurt_Bremser · Accepted solution]

If using wildcards is not feasible, use a macro loop:

%macro combine;
data osumf;
set
%do i =1 %to 10;
  %do j = &i. %to 10;
  osum&i.f_&j.
    %end;
%end;
; /* this ends the SET */
run;
%mend;
%combine
