Nick Winter (!= myself) raised a good point about this. 
My own posting earlier was mostly fixated on the syntax
issue. 

It makes a big difference, namely the difference 
between putting everything in one file and separate 
results in separate files. Computing time is 
a side-issue. 

With the former, presumably -dsconcat- would be 
unnecessary. 

To add more, we'd need to know more about the real problem.
