me neither. I guess OP is working in the unified field theory area as 
one of the the string theories (M-theory) contains 11 dimensional 
space-time continuum for it to be correct. But 1000 dimensions is 
something I can not understand. May be a new theory is in the works?

That is very interesting. I will definitely need to convert some Ada 
code I wrote that uses 2D grids for solving a PDE using this new 
construct to see better how it works. I hope GNAT supports this new 
feature, I will have to find out.
