many games in one PGN


Ooooh. But as soon as you provide that feature (it's like a discover attack) the next shoe to drop will be the desire for a filter so that, for instance, all the games where a player plays as white are selected, or all the wins are selected.
That feature will not be so easy to code, but perhaps one for the Big List of Future Cool Stuff for Students of Chess.
When I download a pack of games from chessgames.com, they come all in one PGN file (not a ZIP of different PGNs). The cool thing about that is that I can import them into BookUp and have a complete repertoire, ready to analyze and annotate. Shredder also treats PGN files as databases that hold multiple games.
I'd like to download the entire record of my games and import them into BookUp for study, but the way PGN downloads work makes it extremely laborious.
I bet the code for doing this is very straightforward... 15 minutes of Perl coding...
Of course, I have a workaround. I could write a Perl program myself to do this, and I will. But I'm thinking of all the non-programmer chess players who wish to analyze their historical games, or who wish to prepare for a tough opponent.
