Hallo Patryk,

Yes, for example for the new sound and graphics commands.

The difference just didn't make me aware of the extra variables but 
also gave me a number. 

Here is a text copy of one of the pages of my PDF:

1C00 ====> -----------

   Misc. Buffers

1000 ====> -----------

   Misc. Variables

0800 ====> -----------

   Text Screen

0400 ====> -----------

   Common RAM

0000 ====> -----------


We can do two things:
- leave the variables on the same place which means we have 5100 
bytes less free for our BASIC programs
- look for another place for them. That's why I mentioned the $Cxxx 
area.
