HI,
I am trying to concatenate 3 datasets (QCdata_1, qcdata_2, qcdata_3) with same structure.
If I try
%MACRO DO_SET;
%DO I = 1 %TO 4;
DATA finalQC;
APPEND Qcdata_&I;
%END;
%MEND DO_SET;
%DO_SET;
It is fiving me error for append.
If I try SET only the last dataset is retained.
Please help.
Thanks,
Archana
Do this:
%macro do_set;
data finalqc;
set
%do i = 1 %to 4;
qcdata_&i
%end;
;
run;
%mend;
%do_set;
Do this:
%macro do_set;
data finalqc;
set
%do i = 1 %to 4;
qcdata_&i
%end;
;
run;
%mend;
%do_set;
If I try this, I am getting

Look again at my proposed solution, and compare it to your code.
You will find that you added a semicolon (that does not belong there) in your log line 6907.
As an exercise in macro programming, try to find out why it must not be there.
Thanks a lot!
I think ; should not be included becasue the format to concatenate datasets is:
DATA xyz;
Set a b c d ;
Set, followed by all datase's name folllowed by ';'
Thanks,
Archana
Well done, young padawan!
😉
This is why I always put macro statements (that need a semicolon to complete) and text that will be created by the macro on separate lines.
