It is the thing that I was talking about (dos games problem). So you  
answered on my question. The differences between fpc and tp is in memory  
allocation. TP gets random state, and it may be unclean from last time,  
and fpc returns mem to OS (and it's clean) and on the next startup I have  
clean memory. I have somewhere some extras pointers and in fpc they point  
to free mem ('' strings) so I don't see the bad result of printing and in  
tp I see them.
Daniël, thank you for help! Now I understood the root of the problem.

I will consider it.
