That was easy. But if I use the preprocessor statement to generate map150,
which is derived from map50, then I do not get map149. Is it correct? So
then I need to write for each map I am going to use a separate preprocessor
statement. Is it so, or do I oversee smth?

Thanks in advance,
Ovanes

Because they weren't designed that way.  If you want to pass 7 arguments,
use map7<...>
