There are times when we need to create a new variable by using variables that reside in separate data files. Circumstances such as these require that we merge, or join, two datasets together.
IF / ELSE DO syntax can help you remove redundant code that comes along with standard IF statements.
IF and Else statements offer an easy way to recode variables in SAS datasteps.
The subsetting IF and WHERE statements are the primary ways through which you filter out records from input data.
Many SAS procedures offer ways to shorten your code.
SAS datasteps can output datasets as permanent, and create multiple datasets with minimal code.
Datastepping is the fundamental input/output method SAS uses to process data.
Writing comments is the quickest way to document programs and makes sharing code easier.
Libnames are the primary tool through which SAS inputs and outputs data.
