Anyone aware of a way to do a mass edit of the header in a pgn file that has multiple games?
Currently I've tried using pgn-extract and the line I have tried is:
pgn-extract -C -N -V -newfile.pgn oldfile.pgn
This does cleanup any annotations in the moves list but the header still remains the same.
Here's an example of a header. In the below header example, say I'd want to get rid of the "Round 29" portion .
[Event "F/S Return Match"] [Site "Belgrade, Serbia JUG"] [Date "1992.11.04"] [Round "29"] [White "Fischer, Robert J."] [Black "Spassky, Boris V."] [Result "1/2-1/2"]
