Reinaldo,
IMO, the fact that we are trying to acquire ER, it is not related at all with the fact that FWH is already compatible with other reports engines, as many of you are already using those other report engines that you mention.
In other words, you are free to use whatever report engine you want to. Thats fine. But in the case with ER, what we want is that all FWH users have already a great report engine included for free with FWH.
And the real advantage of using ER is that we will have its full source code so we will be able to enhance it, modify it, fix it, etc. something which it is totally impossible using a closed commercial reports engine, where you don't have their source code, and just have a closed DLL that if for any reason it gets
discontinued, you will have no way at all to do anything at all.
As an example, please compare xbase++, or Visual dBase, or Visual FoxPro, or CAVO, or VB, etc. with the compiler that we all use today: Harbour. Whats the difference ? Why did you choose you use Harbour ? Because it is free, it is open source code, and we do know that it will exist for ever
