Using the APPEND statement, output data can be created within Proc IML. Using Proc Append within a macro do loop, output can be concatenated from multiple, separate Proc IML calls within that macro.
My question concerns concatenating or updating output data within a do loop from a single Proc IML call. The APPEND statement only retains the most recent value from the loops. I would like to track the successive values within each iteration of that loop. So, if the loop iterates 100 times, then there would be 100 values appended to a single output data set.
Is this possible in Proc IML?
