SAS arrays are another way to temporarily group and refer to SAS variables. A SAS array is not a new data structure the array name is not a variable
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
SAS Arrays. 344. GIORGIO RUSSOLILLO - Cours de préparaGon à la cerGficaGon SAS «Base Programming». A SAS array is a temporary grouping of SAS variables
Sans les arrays. • On répèterait 5 fois le traitement SAS documentation. Page 10. Notation utilisées array note {5} note_francais note_math note_anglais.
Multi-dimensional arrays have lower and upper bounds for each dimension. • Array reference. Specifying an array element or elements in a SAS statement is known
EXAMPLE 1: USING A ONE-DIMENSIONAL ARRAY TO PERFORM REPETITIVE CALCULATIONS. TASK: You want a SAS data set with both the off-season and seasonal rates. The
A SAS array is a set of variables that are grouped together and referred to by a single name. These variables are known as elements of the array. Each element
Arrays are SAS data step statements that allow iterative processing of variables and text. We will look at many examples including 1) input and output of
These arrays can be used to construct a wide variety of other arrays using the methods described with the orthogonal array lists. Note however that the SAS
Familiarity with basic DATA step programming and array processing will be assumed. INTRODUCTION. The SAS Institute is strongly committed to backward
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
Using Arrays with Functions and Operators SAS has many functions and operators that you can use with arrays to perform common tasks This section discusses the following functions and operators as they relate to arrays: DIM function OF operator IN operator VNAME function DIM Function
There are two types of arrays that can be specified in SAS The first is what I call an indexed array and the second is a non-indexed array All arrays are set up and utilized within a DATA step The syntax for an indexed array is as follows: ARRAY arrayname {n} [$] [length] list_of_array_elements; where ARRAY arrayname {n} [$] [length]
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 DO Loops and Why? SAS Array provides a different way to reference a group of variables Reference to the Array elements can be done using DO loops DO loop should have a corresponding END statement (Caution !) within a single DO loop multiple arrays can be referenced and operations on different arrays can be performed 6
Paper 519-2013 Arrays – Data Step Efficiency Harry Droogendyk Stratia Consulting Inc Lynden ON ABSTRACT Arrays are a facility common to many programming languages useful for programming efficiency SAS® data step arrays have a number of unique characteristics that make them especially useful in enhancing your coding productivity
