Just look at the source code of the cbm_* functions how they use the 
kernel functions.  In the case of `cbm_read()` you will even find a C 
implementation in the comments of the assembler source file.

If you don't want to show the actual code then reduce the code to a 
small but runnable example which still has the problem.
