Testing ZW 5

Since testing of all the possibilities of the ZW calculating machine turns out to be a very big task, I would like to ask you for a little help.

My intention is to build a large test-suite of many regattas that I can run and recalculate automatically overnight. That way I can be sure that all calculations will remain correct over time. Or that I need to do some more work.

So, please send me your *.zw files that I can use to this end. Doesn’t matter how old or how big. But preferably regattas with handicaps in them. Or other specials that you can think of.

You can mail them to zwscoring(at)zw-scoring.nl, preferably with a short description indicating what I should pay attention to for your event. I can’t guarantee I’ll reply to your mail, but your effort is always appreciated.



Ps (at) is @ of course 😄

Summer break is over

This weekend I started working again on ZW 5 with fresh enthousiasm!

I left off a few months ago when I was working on the subfields. Got stuck a bit then, which bugged me a little all summer, but this weekend I made great progress. Almost done, finishing up some loose ends and still some testing to do. Next sub-project is entering finish scores.

To be honest, when I started this I didn’t think it would take me (at least) two winters to rebuild this amazing program. That was a bit naive, but had I known I still would have done it. It’s a great challenge. All the more respect for what Leo created.

So, thanks for your patience. I will try to post an update every now and then. In the meanwhile I’m working hard to get a beta version out somewhere in the next half year. No promises 😄

Progress update

Since Visual Studio 2019 came out last week, I will be converting from VS 2017 soon, to keep up with the latest technologies.
In the meanwhile, ZW 5.0 now calculates and prints correctly for fields and subfields.

Only a few more forms and lists need to be done, but experience from the past year tells me that it will still take some time before I can start rolling out.

So please be patient a little longer, I’m working as hard as I can to get a new version to you as soon as possible.



The new ZW version can support many languages, just as the previous version does. I added new texts, and many old ones need to be reviewed or corrected.

At the moment Dutch and English are complete, I can manage these on my own.
For Italian some work needs to be done.
French, Spanish, German and Polish need a lot of work. Especially the Polish, since at some point in the past, due to UTF problems, the correct characters got misformed.

At the moment there are some 1200 texts present in the system. When you are up for translating texts in any of these languages, or even other ones, please drop me a mail at zwscoring@zw-scoring.nl. I will send you an Excel sheet with about 100 texts to be translated or reviewed from English, or one of the other languages if you want, to yours. When you are not fed up after these 100, you can get more.

I’m looking forward to your mails!

Working hard to deliver ZW 5

I admit it has been a bit quiet here, but not to worry. Behind the screens I’m working very hard, almost daily, to rebuild ZW. However, this is not an easy nor a small task.

Yet, I have worked out the main structures and a lot of forms are working. Everything related to the user interface I have had to rebuild mostly from scratch and the particular ZW details I have to convert.

Today for example I spent most of the time documenting the old program where the printing and other output is done. Because newer techniques are available I will have to rebuild this completely.

Next two months I will be finishing up a lot of loose ends, I strive to have a non beta version out before Easter, albeit it may not have all the exotic functionality of the old ZW. That may come later.
