Thank You for answer

That's clear (however I must use in script some sophisticated C++ classes 
(IBPP)  which use smart pointers and templates - that's another challenge 
for me)

I think I understand.

So, rather then include link to another script in script itself - You said 
I must rather load script in C using lua_loadfile and assign to variable.
This is what I can't understand.
Also this common script will contain a lot of shared functions (for 
example to draw report elements like tables,comments - particulary I want 
to generate reports using Lua to build report preview from simple chunks 
and data returned from SQL database).Could You give me an example how to 
load common script from buffer to Lua global variable available to ANY 
script loaded from remote SQL database after that ?


I appreciate any help.
