ERROR 180-322: Statement is not valid or it is used out of proper order.

would you please let me know why is that? Thank you.

There's nothing wrong with the macro, but if you invoke it outside of a data step it's just generating invalid syntax.

Just use it in a data step:

data want;

set something;

%label(x)

run;

Or use PROC DATASETS to avoid recreating the dataset.
