4.9: Managing SAS Datasets with PROC DATASETS 1. Obtain Dataset
Information 2. List Datasets Contained In a Library 3. Copying
Datasets/Catalogs 4. Renaming Datasets/Catalogs 5. Deleting
Datasets/Catalogs 6. Modifying Datasets/Variables 7. Copy the
Label from var1 to var2 in the same DATA Step 8. Completely
Remove Assigned Formats from Variables in a Dataset 9. Append
two or more SAS Datasets PROC DATASETS manages SAS datasets.
This procedure does what other data management techniques can do
(such as the DATA step); however, it will likely perform them
much faster and more efficiently. After you have written SAS
datasets, this section demonstrates a few applications how to
modify their contents with PROC DATASETS. Like so many other
features of SAS, when it comes to data management or statistical
analysis, there are often several methods to accomplish the same
result. For changes to a SAS dataset that do not involve
manipulating the actual data, the DATASETS procedure
substantially improves efficiency in both
