Non-temporary data step arrays demonstrate the real flexibility and versatility of SAS arrays These types of arrays can refer to a series of variables already present in the program data vector ( PDV ) or even create variables while permitting those variables to be referenced via array structures
What is SAS array?
- SAS ARRAYS 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.
How does SAS determine the number of variables in a weight array?
- Notice the asterisk (*) inside the brackets in the WEIGHT array above. SAS must be able to determine the number of elements or variables in the array when it compiles the code. SAS determines this either by using the constant value that is specified in the brackets or by counting the number of variables in the variable list.
Why is a variable list not specified in SAS?
- Because a variable list is not specified in this example, SAS uses the name of the array (WEIGHT) and adds a numeric suffix from 1 to 10 to associate or create the specified number of variables with the array. Note: SAS must be able determine the number of elements or variables in the array when it compiles the code.
Can a SAS code be written without arrays?
- In nearly all cases, code that is written with arrays can also be written without arrays. Arrays simply provide an alternative method for referring to a variable rather than using the name of the variable. To use arrays in SAS code, first make sure that you understand the basic syntax of the SAS ARRAY statement.
