I am executing sas remotely on my university servers and using the OPTMODEL proc. This is a simple LP and I would like to know which constraints are binding. For this purpose I can look at the dual variable of a constraint. However the constraints are indexed by multiple indices based on the number of nodes in a network. Which means for each set of nodes [i,j] I have a constraint. This forms a matrix of dual variables and I can use CSET1[5,7].dual to refer to constraint regarding nodes 5 and 7 in constraint set CSET1. How do I export these dual values to a csv file?
