DATA sales; INPUT region $ salesrep $ sales amount; LABEL region = 'Region' salesrep = 'Sales Representative' sales = 'Sales Amount'; FORMAT sales dollar10.2; INFILE 'sales_data.txt'; /* data manipulation statements */ RUN; The PROC SORT procedure is used to sort a SAS dataset in ascending or descending order.
In this paper, we have discussed various data manipulation techniques in SAS programming, including DATA step, PROC SORT, PROC DATATYPE, PROC TRANSPOSE, MERGE, UPDATE, ARRAY, and DO LOOPS. These techniques are essential for any SAS programmer to manipulate and prepare data for analysis. With practice and experience, SAS programmers can efficiently use these techniques to manage and analyze large datasets. Sas Programming 2 Data Manipulation Techniques Pdf 17
DATA sales_array; ARRAY sales-array 4 sales1 sales2 sales3 sales4; DO i = 1 to 4; sales-array(i) = sales * i; END; RUN; The DO LOOP statement is used to execute a block of statements repeatedly.
1. Data Step The DATA step is used to create and manipulate data in SAS. It is the primary step in SAS programming where data is read, processed, and written to a SAS dataset. PROC SORT DATA=dataset-name; BY variable1 variable2
SAS (Statistical Analysis System) is a powerful software tool used for data analysis, data management, and data visualization. In SAS programming, data manipulation is a crucial step in preparing data for analysis. This paper focuses on various data manipulation techniques in SAS, which are essential for any SAS programmer. We will discuss the concepts, syntax, and examples of different data manipulation techniques.

DATA sales_loop; DO i = 1 TO 10 BY 2; sales_loop(i) = sales * i; END; RUN;
DATA output-dataset; DO variable = start TO end BY increment; /* loop statements */ END; RUN;
