I need to put observations in five dataset into one dataset. I usually use macro and loop, each time with data step setting two dataset. I think this way is not efficient. Does anyone have a better solution to merge five dataset in one piece of code? The variables sometime do not have the same name. But they are the same thing. It is basically just putting observations in different dataset into the same dataset. Thanks!
If by merge you mean concatenate then use rename to get uniform names and simply list the datasets in a set statement:
data all;
set
dset1 (rename=(oldvar1=newvar))
dset2 (rename=(oldvar2=newvar))
dset3 (rename=(oldvar3=newvar))
dset4 (rename=(oldvar4=newvar))
dset5 (rename=(oldvar5=newvar));
run;
