In a subsequent posting, the use of setting the file type to binary in
Kermit was on for the local download was indicated.

With the very broad exception of the emTeX files or files with PKUNZIP
actually in the directory, UNZIP (5.0) is supposed to be used on files from
SHSU.  Since DVISPELL.ZIP is from emTeX, PKUNZIP is appropriate.  A very
general guess on this is that your parity is messed up somewere. 
Unfortunately, the variety of Kermit utilities on VMS vary widely in their
defaults.  I seem to recall that MS-Kermit uses even parity; Kermit-32 and
C-Kermit on VMS both default to no parity.  In just about every case where
VMS has been involved which has been brought to my attention, it was a
parity problem.  My real puzzle here is how you got UNZIP from SHSU to
work.

Are you sure that the system-level Kermit didn't change on the VMS side?

You need to concatenate the files (in VMS, you can generally use the APPEND
command verb to create a file, or use EVE or some other editor to simply
include the files into one another).  Once concatenated, strip out any
headers so that you have a file which is 61 characters wide and full of
absolute nonsense.  This is were editing on the fly for concatenation comes
in handy.  

Use the UUDECODE utility to decode the nonsense into its original file
format.  In the directory [FILESERV.UUCODE] on Niord.SHSU.edu
(192.92.115.8) is a set of files for the UU*CODE suite.  The C sources are
for just about every platform.  There is also a copy of the executables for
VMS, as well as a command file to make these in VMS. You may also retrieve
these via e-mail by including:
 SENDME UUCODE 
in the body of a mail message to FILESERV@SHSU.BITNET (FILESERV@SHSU.edu).

On DOS and Unix there are some scripts to do this automagically.  Once the
VV*CODE suite is available, we will probably migrate to that as it is an
awful lot smarter and takes away the concatenation nonsense.  The betas on
VV*CODE which I have used are marvelous, BTW.
