[fwtools] help with fwdoc_used_objects.py

I'm almost embarrassed to post this, because I'm likely doing something very 
brainless.  On Windows XP, using Python 2.5, I'm experiencing the following 
(I've broken out the process steps for clarity):

   C:\FW\Working Files>fw1r55_to_fwdoc.pl --with_implicit_rules 
--merge_AI=rulebases_5_0.fws --rules=myrules.W --objects=objects_5_0.C 
--verbose > fwdoc1.txt

   Reading Done.

   Printing ruleset to FWdoc into STDOUT.

   Done.

I can verify that the output of fw1r55_to_fwdoc.pl is produced just fine.  
Next I attempt to pass my output file (fwdoc1.txt) as input into 
fwdoc_used_objects.py:

   C:\FW\Working Files>type fwdoc1.txt | fwdoc_used_objects.py
   The process tried to write to a nonexistent pipe.
   Traceback (most recent call last):
     File "C:\FW\Working Files\fwdoc_used_objects.py", line 56, in 
       fwdoctxt = sys.stdin.read(MAXSIZE)
   IOError: [Errno 9] Bad file descriptor

Any idea why this is occurring?  I get roughly the same result with 
fwdoc_to_html.py and fwdoc_to_txt.py:

   C:\FW\Working Files>type fwdoc1.txt | fwdoc_to_html.py
   The process tried to write to a nonexistent pipe.
   Traceback (most recent call last):
     File "C:\FW\Working Files\fwdoc_to_html.py", line 45, in 
       fwdoctxt = sys.stdin.read(MAXSIZE)
   IOError: [Errno 9] Bad file descriptor

   C:\FW\Working Files>type fwdoc1.txt | fwdoc_to_txt.py
   The process tried to write to a nonexistent pipe.
   Traceback (most recent call last):
     File "C:\FW\Working Files\fwdoc_to_txt.py", line 45, in 
       fwdoctxt = sys.stdin.read(MAXSIZE)
   IOError: [Errno 9] Bad file descriptor

If I replace "|" with ">", I get no output at all:
   C:\FW\Working Files>type fwdoc1.txt > fwdoc_to_txt.py

   C:\FW\Working Files>

I'm obviously doing something dumb, but I suppose I'm too close to it to see 
my error.
Any suggestions?

Regards,
