Of course. When doing VMS zips, I always add "-V" without thinking, 
because that is what I need most of the time.

Removing the "-V" brings the remote zipper process to an end without 
errors. I wind up with an archive that unzip sees as:

$ unz -v remote
Get RMS defaults.  getjpi sts = %x00000001.
                Default: deq =      0, mbc =   0, mbf =   0.
Open callback.  ID = 1, deq =  16384, mbc = 127, mbf =   2.
Archive:  SYS$SYSROOT:[SYSMGR]REMOTE.ZIP;1

Now my saveset is called "-", how to extract it with a proper VMS name? 
The saveset attributes may be fixed afterwards with the usual tweak I 
hope. And "stored"? Hmm. The actual backup command at the sending end was

$       blocks = 4
$       bytes  = 512*blocks
$       set rms /net='blocks
$       backup *.COM 0::"task=ZIPPER" /sav /block_size='bytes

Just a bunch of command files from SYS$MANAGER. When I zip 'm locally I get:

$ bac *.com local.bck /sav
$ zip -v local local.bck
   adding: LOCAL.BCK     (in=999936) (out=320889) (deflated 68%)
total bytes=999936, compressed=320889 -> 68% savings
$ unz -v local
