I don't think there's a contradiction : after all, MetaCard stacks are entirely RAM-based so it should be no slower to access a variable than to access the contents of a field. In the old HyperCard days, its engine had to load the field text from disk, and every manipulation meant writing to disk, updating the hintbits for its quick find algorithm etc. But I'm sure there'll be a performance hit when you manipulate the contents of a field in a repeat for each loop, as the screen needs to be redrawn. Of course only Mr Raney knows for sure, but I think the content isn't copied, and that during a 'repeat for each' the engine merely remembers the last line delimiter position and the next line delimiter position as it munches away the data.
