Arrays are temporary processes to perform repetitive calculations to a group of variables within a data step (SAS. Healthcare Providers & Insurers. SAS Global
Basic Syntax of the ARRAY Statement To use arrays in SAS code first make sure that you understand the basic syntax of the SAS ARRAY statement This section describes the ARRAY statement and provides a number of examples to illustrate its use Subsequent sections progress to more complex statements and examples
SAS ARRAY is a set of variables of the same type called “elements” of the arry that you want to perform the same operation on An array name is assigned to the set of variables Then the array name is reference in other DATA step programming to do an operation on the entire set of variables in the array
SAS ARRAY is a set of variables of the same type called the “elements” of the array that you want to perform the same operation on An array name is assigned to the set of variables and then the array name is referenced in later DATA step programming usually a DO loop to do an operation on the entire set of variables in the array
A SAS array is a convenient way of temporarily identifying a group of variables for processing within a data step Once the array has been defined the programmer is now able to perform the same tasks for a series of related variables the array elements
the array ( A numeric constant/Numeric SAS expression /(*) [$] - used to specify if the elements in the array are character variables the default type is numeric [length] - used to define the length of new variables being created in the array optional array_elements - a list of variables of the same type (all numeric
A SAS ARRAY is a set of variables of the same type that you want to perform the same operation on The set of variables is then referenced in the DATA step by the array name The variables in the array are called the “elements” of the array Arrays can be used to do all sorts of things
Is array a variable in SAS?
A SAS array is not a new data structure, the array name is not a variable, and arrays do not define additional variables. Rather, a SAS array provides a different name to reference a group of variables. The ARRAY statement defines variables to be processed as a group.
What is an array name?
An array name is assigned to the set of variables and then the array name is referenced in later DATA step programming, usually a DO loop, to do an operation on the entire set of variables in the array. Arrays can be used to do all sorts of things.
Can I put a variable name in a bracket in SAS?
Note: SAS must be able determine the number of elements or variables in the array when it compiles the code. Therefore, you cannot place a variable name in the brackets, as illustrated in the following statement, with the intent of SAS referencing the name to determine the number of elements:
How to specify a list of array elements with the -?
Secondly, we can specify the list of array elements with the “-“ in between the first variable name, q1, and last variable name, q20, because the variables are named with the same root name followed by a number that is indicated sequentially from 1 to 20. EXAMPLE 2 – “RENAMING” VARIABLES
