Re: Commands Writing To Binary File

Andy, there are few problems with that example. write_file takes a sequence of data, not just one atom/integer. You could fix that portion by writing write_file(handle, { data }).

The second problem is write_file returns an integer, 1 for success, -1 for failure. You are assigning that result to file which is a sequence, not an integer. I would probably do something like:

procedure SaveFile(sequence filename, object data) 
    if atom(data) then 
        data = { data } 
    end if 
 
    if write_file(filename, data) = -1 then 
        puts(1, "Cannot write to file!\n") 
    end if 
end procedure 
 
SaveFile("hello.bin", 1) 

The above code also gets rid of external states, and external globals both of which are troublesome once an application gets to be more than a few hundred lines of code.
