Honestly, it's not thought through thoroughly. Just when trying to
extract the filename from the full filename I thought it would be nice
if in above example an expression something like |.*\\Data(.*)\.dat|
directly returned the "007". Well, now I have a rather compact solution.

On the otherhand, when creating a list of data files to be plotted it
would be nice if the search pattern in
  FileList = system(dir /B /S Data*.dat)
could be a bit more sophisticated than a simple wildcard. I know that
this is a Windows system command and gnuplot doesn't have any influence
on it. Although, gnuplot could filter it further and/or "distribute" the
files to sublists which are then plotted in a single plot or multiplot
environment. I need to find a practical example to illustrate. But
probably one can also find a solution with the already existing gnuplot
commands.
I guess a binary regexp test together with the ternary operator could be
quite powerful.
Well, as I said, it's not fully thought out...
