sas array

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

Assigning Initial Values to Array Variables or Elements . program data vector (PDV) when the ARRAY statement is compiled SAS creates them for you.

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 

SAS arrays must contain either numeric or character data not a mixture of both. TEMPORARY ARRAY DEFINITION. Temporary arrays provide convenient tabular data 

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 

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 

Familiarity with basic DATA step programming and array processing will be assumed. INTRODUCTION. The SAS Institute is strongly committed to backward 

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 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 

Arrays are SAS data step statements that allow clever programmers to do a great deal of work with little code. Arrays process identified variables as a group 

SAS programs that are written with arrays can be written without arrays For example suppose you have these three statements that use arrays: do i=1 to 12; net_inc[i] = revenue[i] - exp[i]; end; The same task can be accomplished without arrays by using these 12 statements: net_inc1 = rev1 - exp1;

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

Array Programming Basics John J Cohen AstraZeneca LP Wilmington DE Abstract Using arrays offers a wonderful extension to your SAS® programming toolkit Whenever iterative processing is called for they can make programming easier and programs easier to maintain You

An array in SAS provides a means for repetitively processingvariables using a do-loop Arrays are merely a convenient way ofgrouping variables and do not persist beyond the data step inwhich they are used SAS arrays can be used for simple repetitive tasks reshaping datasets and remembering" values from observation-to-observation

What is an Array? zA SAS array – is a temporary grouping of SAS variables that are arranged in a particular order and identified by an array-name – exists only for the duration of the current DATA step – is not a variable-(SAS online documentation)
