SAS 9.4 Language Reference, 6th Edition

Misc contains eight elements, the variables Misc1 through Misc8. To reference the data

in these variables, use the form Misc{n}, where n is the element number in the array. For

example, Misc{6} is the sixth element in the array.

Mday contains seven elements, the variables Mday1 through Mday7. Mday{3} is the

third element in the array.

The Expenses array contains ten groups of eight variables each. The ten groups (expense

categories) comprise the first dimension of the array, and the eight variables (days of the

week) comprise the second dimension. To reference the data in the array variables, use

the form Expenses{m,n}, where m is the element number in the first dimension of the

array, and n is the element number in the second dimension of the array. Expenses{6,4}

references the value of dues for the fourth day (the variable is Dues4).

Syntax for Defining and Referencing an Array

To define a simple or a multidimensional array, use the ARRAY statement. The ARRAY

statement has the following form:

ARRAY array-name {number-of-elements} <$> <length> <array-elements> <(initial-

value-list)>;

where

array-name

is a SAS name that identifies the group of variables.
