PROC SORT DATA=sales; BY region salesrep; RUN; The PROC DATATYPE procedure is used to change the type of a variable in a SAS dataset.

PROC TRANSPOSE DATA=dataset-name OUT=output-dataset; BY variable1 variable2 ...; ID variable3; VAR variable4; RUN;

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. DATA sales; INPUT region $ salesrep $ sales

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.

DATA output-dataset; MERGE dataset1 dataset2 ...; BY variable; RUN; DATA output-dataset; ARRAY array-name n variable1 variable2

PROC UPDATE DATA=sales; UPDATE sales_updates; BY sales_id; RUN; The ARRAY statement is used to create a temporary array to store values.

DATA output-dataset; DO variable = start TO end BY increment; /* loop statements */ END; RUN;
