Document Summary
Arrays are temporary groupings of sas variables under a single name. Create several variables with the same attributes. Rotate sas datasets by switching variables to observations or vise versa. The array statement can be used with both unidimensional and multidimensional arrays. Arrays can be used to store values from other sas variables, create values for new sas variables, or both. If you are storing values, these values will be stored temprarily. Arrays are only effective within the sas dataset and sas data statement: rules for naming arrays, do not use names of sas functions. Using an array places the results in the respective variables used in the array. If one creates a new sas dataset that is a copy of a sas dataset where an array was used, the array cannot be referenced in the new sas dataset; the array must be recreated. Since arrays are local and temporary, you should note the following characteristics.
