I noticed in a later posting that you were able to solve this problem,
so this is just a (hopefully useful) followup comment.
If curly braces are present in the written output, it is because they
were present in the input. Mathematica doesn't insert curly braces
that weren't already there. For example, if x={3.0123} is written to
a file, the result will include the curly braces. In this example, one
way to get rid of the curly braces is to write x[[1]] instead.
Writing to a file, at least for simple text formats like InputForm and
OutputForm, is no different than writing to the computer screen. One
convenient way to work out the file format that you want is to first
get that output on the computer screen.
