Re: Question of performance
Hi Ragulf, I think, it's more computer- (the memory) or transformer-dependent (the memory-handling). But in general I would use the global variable, because it's better to avoid multiple times the same transformation. So string-manipulation and searching huge input-trees (41 KB isn't really big ;-) some have file sizes more than 10 MB) should be stored in a variable. You wrote you have a complex variable. In which way? Complex string-manipulation, the variable stores only a 'string'. Or must the variable store almost the whole input-file?
