The video tutorial covers common tasks performed on datasets, such as copying datasets, renaming datasets, and renaming variables. It explains how to handle indexes during these operations using the PROC DATASETS procedure in SAS. The tutorial provides syntax examples for each task, ensuring that indexes are preserved or automatically updated.
