I am looking for advice on appending to large mapped files (yes, I confess, it's the Netflix data).
I have a name f mapped to a file containing a list of integers, and I want to append a list a from memory. I am essentially doing this by for_i. a do. additem_jmf_ 'f' f=:i (_1) } f end. Is this what I am supposed to be doing, or is there a better way?
