 		 #141724 - Why?
Responding to: ???'s previous message
Nimish Dave said:
I am working on diassembler program.So the programme has to differenciate between blank space and instruction FF.

Why does it have to do that?

As already explained, the processor cannot distinguish - so there isn't really any reason for a disassembler to do so!

Presumably, though, a disassembler will be reading a file - so it can tell where the end of the file is...
