In case anyone was paying attention to this (now dead) thread, Nick may have
given the best advice.

kws@delphi reminded me of the unix command I was looking for 'od'.  Thanks!
 "od -x SEN0404.DOC" reported the following (lots of stuff zapped).

Offsets on left are octal, I dumped the data in hexadecimal.
My file was corrupt on my IIGS at $0c00 = octal 06000.  But this
dump on the unix box looked correct, so I can assume pine extracts the
attachment without error.  Whew.

Next I downloaded SEN0404.DOC in binary mode using 1) Kermit and 2) z-modem
using Proterm3.1

1) Opened correctly in Word.  Hurray for Kermit.

2) Refused again to be opened by Word.  Bad for z-modem. 

I also note that in the files I've found corrupted, the corruption has
always occurred after a long run of NULLs, $00, in the file.  In the od
dump note that lines 04060 through 05760 are all nulls. (The * indicates
that intermediate lines are identical to the preceding line.)  If my
octal math is right, that is 960 nulls plus a few in the non null lines.

I think zmodem is messing up for some reason.  I'll go out on a limb and
guess it is not IBM's AIX implementation of OMEN technologies zmodem for unix.
Perhaps ProTerm3.1?  Not enough evidence to indict.

But I can trust pine to extract attachments, and if problems arise, falling
back to Kermit (or perhaps ymodem or xmodem) to download a MSWord file
seems to be the best suggestion.  To date, I have not noticed any problem
to using zmodem to download binary files other than MSWord, and zmodem has no
problem downloading the base64 version of the MSWord files.

I think this exhausts my interest in getting MSWord files with my IIGS.  I
have a couple of working solutions.  I don't feel like debugging zmodem :-)

Apple II forever!
