But, but, but... Ruslan... you talk at a different level now. Kernel 
functionality is one thing, calling it from Transcript is another.

Nobody said there should be a difference with syntax of kernel 
functions. What we talk about is the transcript-level coding. Using 
your example above:

in local mode

get Valentina("Cursor_GetRecordCount",cursorRef)

in client-server mode

get Valentina_Server("Cursor_GetRecordCount",cursorRef)

The part in parenthesis is the SAME (as it was in my original 
example). The difference is only in using a different external. 
Whether these externals use the same or different libraries is 
totally irrelevant to us (as long as it works :)

This si why I said that when I have a program that calls "Valentina" 
and I want to SWITCH it to using only server, I just make a global 
change of "Valentina" to "Valentina_Server" and add all the 
server-related stuff.

If I support both modes, I can immediately see which parts of my code 
deal with local database and which with remote.
