Tony, without repeating what others said before about your stunning job (my hat is off to you!), I'm wondering about what you said regarding memory: working on Germany on a system with, let's say, 16Gb ram, do you think there will be still need of disk storage for temporary files (assuming that temp files would be used during the generation)? The use of local storage is a choice done by using one (or more) parameter(s) or it will be managed by the generator in an automatic way? Many thanks in advance! Angelo
