Turing machines don't.

However, I would say that all _useful_, _general-purpose_ languages can 
read and write files.

Having said that, some of them move I/O into standard libraries and 
don't deal with them in the language proper.  In fact, most languages do 
that.

Sometimes domain-specific languages will also lack this feature, because 
it is not relevant to what it is trying to do.
