Hello,

I am having trouble with my database. I am using Euphoria's default EDS. I'll post my code and my error.It says there is a problem with the names. I'm not sure what is going on. Everything appears to be correct. Perhaps the naming scheme is conflicting with something? I don't know.

Ah, I see. Yes I am using Eu4. So that's what I was doing wrong. Thanks.

Well the jury is still out on that one. There are arguments for not having any public variables at all.

With Euphoria, you no longer need to mark your public symbols this way. The namespace concept allows one to name your public symbols however you like and then refer to them using the namespace for the include file.

Eg ...

-- mymod.e --- 
namespace mypub 
public enum  
   NAME, 
   ADDRESS, 
   TELEPHONE 

and then reference it thus

include mymod.e 
  data[mypub:NAME]
