Perhaps the physical simulation example would = like 64 bit addressing, but sparse arrays could be a viable alternative. > Oh, and 8 registers are far too few. Unless you're writing assembler, the compilers hide that. Anyway, I was just curious to see what specific real case you had for = needing 64 bits. Proprietary considerations often get in the way of = that. --lyndon
