SAS data types

SAS has only two data types: real numbers and fixed length character strings. Dates and times are internally stored as numbers.
Macro variables are always characters.
Character values must be quoted to distinguish them from other language elements (such as variables).

Conversion from one to another

Values of one data type can be converted to the other with the input and put function.

Determining type

The type of a variable can be determined with vtype.

In a data step, the variables of a specific type can be referred to with the special variable lists _numeric_ or _character_.
