This is SAS (Statistical Analysis System) code, and here's what it does:

The ARRAY statement is used to define an array in SAS. Specifically, this line:

array df{*} B00211 B00212 B00213 B00214 B00215 B00216 B00217 B00218;

• array df{*}: Creates an array named df and specifies that the array can accommodate however many variables are listed explicitly (the {*} notation allows automatic size determination based on the number of variables mentioned in the list).

• B00211 B00212 B00213 B00214 B00215 B00216 B00217 B00218: This is the list of SAS variables included in the df array.

In summary, this code creates an array called df that holds 8 variables (B00211 to B00218) for reference and processing in subsequent SAS operations. Arrays in SAS allow you to manipulate multiple variables collectively, making it easier to perform repetitive tasks such as looping or conditional transformations.
