Flash programming MC9S08QG8

Dear Community
I wrote an assembler program to store data in the flash of MC9S08QG8. 
It still has errors. The program allows one byte to be saved 
in a program loop in BDM debug mode, 
but not several bytes continuously. 
The required NOPs at the end of the programming loop are also not OK. 
Can you help me?

Now I have implemented my Flash program for writing bytes and 
deleting byte blocks in assembly code.
The community helped me with this, but I don't know how to 
give kudos to the answer authors.

Another interesting observation when using the Flash routine:
When I test the routine with a chip that has been used for a long time,
it happens that some bytes in the deleted block are not deleted.
If I write and delete in a higher, less used program area, 
this doesn't happen.
Thank you to the community

Next time I would like to ask my questions about transferring 
the measured values to a PC.
With best regards
Gerd
