A "fillword" procedure does not exist. FillChar is an anchient Pascal 
function to simply fill any arbitrary memory location of any size 
(determined by a variable) with all the same byte. It is very fast but 
there is no type checking at all (you can fill any type of variable) and 
I think there is no range checking either. So you should use SizeOf() to 
  give the number of bytes to be written but in special circumstance you 
can also use a different value.

A similar procedure is move, which copies bytes from one memory location 
to another (again both determined by variables) also without type and 
range checking.
