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 TRANSPOSE DATA=dataset-name OUT=output-dataset; BY variable1 variable2 ...; ID variable3; VAR variable4; RUN; It is the primary step in SAS programming

Here are some common SAS data manipulation techniques:

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. BY variable1 variable2 ...

DATA dataset-name; INPUT variable1 variable2 ...; LABEL variable1 = 'label1' variable2 = 'label2' ...; FORMAT variable1 format1 variable2 format2 ...; INFILE 'file-name'; /* data manipulation statements */ RUN;

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

DATA output-dataset; MERGE dataset1 dataset2 ...; BY variable; RUN;

PROC DATATYPE DATA=sales; CHANGE sales = numeric; RUN; The PROC TRANSPOSE procedure is used to transpose a SAS dataset from rows to columns or vice versa.
