SAS Loops - DO LOOP Syntax DO value = start TO stop Example data data_bin; do i = 1 to 4; y = i**2; output; end; run; Output 2, 5, 9, 16, 25 The SAS loop comes to a close with the END statement. WebbFirst, we create a new variable, balance, and set it equal to 300000 (assuming the balance of your mortgage is $300,000). Next, we would like to loop through 52 weeks (1 year) with bi-weekly payments. So, in SAS terms, we will iterate the index variable “i" from 1 to 52 by 2, since we want bi-weekly payments spread across 52 weeks.
