>Thanks! I've followed the example in lua.c, and it seems to work. I have just

lua.c takes special care with errors and so at that point uses lua_rawget
instead of lua_gettable, which is what lua_getglobal does. lua_pushliteral is
a simple macro that avoids the call to strlen in lua_pushstring when you use
literal strings. You can use lua_getglobal.

Yes, you can set 'debug' to nil after loading dblib. But perhaps you can just
copy errorfb from ldblib.c into your code and not load dblib at all.
