I have made some progress on the creation of a hexeditor program for 
RS-DOS.
It is able to display the contents of a file in hexadecmal 80 Bytes at a 
time in
10 rows of eight hex numbers for each row. I also have the code to  pick 
any
entry and change it's value. However somehow this is not getting saved 
back to the
direct assess file.

I am attaching a test program based on my attempts to open a file make 
changes and
then save it back. It does not work correctly and  am at a loss to 
understand why
could you please look at the code in the attached file and tell me where 
I went wrong.

Much Thanks
