thank you for your exaustive reply. To be more clear, I'm actually
using IBO 4.3Aa (native components). To summarize all what you have
said I think that the best thing to do is to use explicit
transactions, unless there is only one cursor to work with:

1. One separate explicit transaction for every cursor
to open (and browse)
2. A second explicit transaction to make changes to
the above cursors

I hope that this is the right way :-)
