YOU ROCK ANDREAS!
I simply put my command in a file and rrdtool ran that command most excellent using rrdtool - < doit.txt
The command called in over 164 files with the appropriate sum CDEF on it etc.. etc.. it was over 3 thousand characters long and rrdtool complied the graph in less then 2 seconds. I am most impressed at the person that codded it!

Never used rrdtool in a DOS/Windows environment, but ...
You can - at least in a UN*X environment - run rrdtool in the so called "pipe mode" by calling:
Maybe you can try this and feed your command through this pipe.
(Even DOS can do standard I/O redirection, right ?)
