I am currently debugging a app which sometimes reacts strange.
The author of this app is not available, and there is almost no comment in the source.

Now I found some code which seems a bit strange to me:

     ...
     JNB RI,$
     CLR RI
     MOV chksum,SBUF
     MOV var,SBUF
     ....

I know that this not the right way to read sbuf but
the my question will be :
What value will be into <var>?
The same as in chksum or some other value ?

Any ideas ?
