Working with Numeric Variables

Abbreviating lists of variables: Ways to abbreviate lists of variables in function arguments are documented in SAS Language Reference: Concepts. Many functions, including the SUM function, accept abbreviated lists of variables as arguments.
DEFAULT= option: Information about using the DEFAULT= option in the LENGTH statement to assign a default storage length to all newly created numeric variables can be found in SAS Language Reference: Dictionary.
Logical expressions: Additional information about the use of logical expressions can be found in SAS Language Reference: Concepts.
Numeric precision: For a discussion about numeric precision, see SAS Language Reference: Concepts. Because the computer's hardware determines the way that a computer stores numbers, the precision with which SAS can store numbers depends on the hardware of the computer system on which it is installed. Specific limits for hardware are discussed in the SAS documentation for each operating environment.
Saving space: For information about how you can save space by treating some numeric values as character values see Working with Character Variables.
