Suggest you use a macro variable declared with a %LET statement to identify the maximum array element/variable.

I could be wrong but I think you want to use the regular data step do loop instead of %do. %Do is something you should use if you want to iterate blocks of code such as series of data steps or procs. I dont think %do can access the array in the data step.
