I wonder if it has to do with the OS-dependent line-ending conversion 
that the engine does when it writes to text files. If you open the file 
as binfile instead of plain "file" you'll avoid that conversion. It 
might work differently that way.

That looks right. The "write" command always begins writing at the 
postion after the pointer. But when you specify an exact postion in 
particular, it writes where you tell it.
