  Wow! This is most interesting! I think this is true for embedded
control programs like I suppose yours are, but is it also true for
more general purpose programs?

   In the light of "need to present Forth to academic community at large"
thread, please please do try and publish in more "main stream" journals!
JFAR, and Forth Dimensions are not read by so many, and those who
read are already "converted" anyway !!

   I await the publication of the paper.
