Thanks for your response, Alex.  I was wondering in what context I
should use that within the program itself?  I am fairly new to Python
and have not found very many references in the books that I have read
that would show the exact sequence on when/where I would put that
string/command into effect with the code itself.

Basically, I am defining the command to
def FindFibBetween(A,B), having it go through the simple sequence of
getting the numbers, and then they output them to a screen.  I want to
interven so that it will NOT print them to a screen, but dump them
directly into a text file.

So what I need to know is at what point to I call it in the program to
open a file, write the numbers to it, and then close the file?

Here is the complete code that I use so far:

def FindFibBetween(A,B):
  x, y = 1L, 1L
  while x < B:
    if x >= A: print x
    x, y = y, x+y

then I input FindFibBetween(1, 100) or whatever range for (1, n)

Thank you for your time and assistance.

Eric
