![]() ![]() You'll find more tips like this one in my book, PROC SQL: Beyond the Basics Using SAS, Second Edition. This tip explores a few ways to determine, or estimate, the size of a data set – a question many users are curious about when discussing SAS performance and tuning techniques. To access, for example, how much disk space a data set is using, users can make a few calculations and/or learn how to access metadata content to obtain the information to this important information. Since data sizes and system performance can affect a program and/or an application’s behavior, SAS users may want to access information about a data set’s content and size. When developing SAS® data sets, program code and/or applications, efficiency is not always given the attention it deserves, particularly in the early phases of development.
