Yes, it is intentional. That a blank line got written after a single record (only) was regarded as unintentional: blank lines are (I was told) record separators and not terminators. > frame to DCF format one row at a time, so I make use of repeated calls > to 'write.dcf(append = TRUE)'.

But surely it is better to keep a connection open and make repeated calls to write.dcf on it (as write_PACKAGES does). I don't think writing record separators explicitly is much of a hardship. > It seems the only way to use 'write.dcf(append = TRUE)' is to > explicitly write a blank line to the file before writing the entry. or after an entry. > Perhaps 'write.dcf' could be changed to write a blank line in the > beginning if append = TRUE?
