For me it's not clear what you want to do: I understand, that the 20 datasets have common variables with different labels. You want to give the variables new labels... Is the 20-datasets-list fix or do you need it dynamicly ("each dataset in a lib, ...)? where do the labels come from? Do you key them in? Do they come from one of the datasets? Wich one is the "master"? Are only the common variables to be labeled? Is this a "one-time-task" or do you need that often? If one-time, open the dir window and from there all variable-list windows, then use "r"(ename) to assign the new lables. If you need that often, use a macro with

... PROC DATASETS....; MODIFY sas_ds LABEL=...; run; ...
