      SAS arranges columns in a dataset according to the order in which the variables are declared or defined, so any variables declared prior to the SET statement will be placed first in the resulting output dataset. However, unless the sole purpose of a datastep is to re-order variables, the use of RETAIN for this purpose can lead to unwanted side
