Arrays in the SAS language are different from those in many other languages. A SAS array is simply a convenient way of temporarily identifying a group of variables. It is not a data structure, and array-name is not a variable. An ARRAY statement defines an array. An array reference uses an array element in a program statement.

If you want to use the same array in several DATA steps, redefine the array in each step. You can specify character variables and their lengths in ARRAY statements. The following example groups variables into two arrays, NAMES and CAPITALS. The dollar sign ($) tells SAS to create the elements as character variables. If the variables have already been declared as character variables, a dollar sign in the array is not necessary. SAS software array and associated do loop statements with the idea of translating those concepts into SAS software macro language usage. SAS array statement & dimension (dim) function The explicit array statement in SAS software has seven phrases; we will examine the four that are most commonly used: 1.

Instead of referring to the first revenue variable as Rev1, you can refer to it by using the array name and an index into the array, such as REVENUE[I] (assuming that I has a value of 1). Using Arrays with Functions and Operators A SAS array is simply a convenient way of temporarily identifying a group of variables. It is not a data structure, and array-name is not a variable. An ARRAY statement defines an array.

The name of the underlying Iteration of SAS code is often easily achieved with the use of Macro Arrays. the assignment of values to macro-variable array elements using CALL Array elements don't need to be contiguous, the same length, or even related at all. All elements must be character or numeric. Why do we need SAS arrays? Jul 24, 2018 end ;.

Such data sets have one observation per subject and multiple time points and variables within one row. Jennifer Wa In SAS, an array is created with the array statement within a data step. Arrays can be useful in very explicit ways, like creating or modifying a series of variables, and in more subtle ways, like reshaping a dataset or comparing across observations.
