Arrays in data step

Arrays are used in the data step.

SAS arrays are just 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, and arrays do not define additional variables.

  • Rather, a SAS array provides a different name to reference a group of variables.

Arrays in macros

The macro statement %Array(V,A B C) produces three macro variables, V1, V2, and V3, with corresponding values: A, B, and C and macro variable Dim V with the value 3.

These variables can then be used in the macro iterative loop statement %Do I = 1 %to &Dim V.;
