The BEST D formats that you have ever seen!

The Dw.p format displays numeric values, in a field w positions wide, possibly with a great range of values, lining up decimals for values of similar magnitude. The BESTDw.pformat combines the BESTw. format for integers and the Dw.p format for nonintegers. Specifying BESTDw.p (where p = w - 1) is better than specifying BESTw. for columns, since decimals do not shift when the last digit is 0.

However, SAS 9.4m1 introduced the SMOOTHCONNECT option which, as the name implies, uses a smooth curve to connect the observations. In Sanjay Matange's blog,

The Little SAS Program’s Big Night Out

The little SAS program’s official name was Extract_Transform_Load_ 0314.sas. But, that name was much too formal, way too long, and did not roll off of the tongue very easily at all. So, everybody simply called her: ETL Pi. ETL Pi was conceived in a 2-hour project strategy meeting in conference
