Is there any reason you can't use jar or ajar? For example,

jar uf FROBOZZ.zip REZROV.pdf

(I have not tested that on the i; but that jar command is supposed
to do exactly what you are asking.)

QSHELLing out to JAR *works* but it has a *massive* performance hit
compared to ZLIB/ZIP:

Generating 85 reports, discarding any existing ZIP files, and ZIPping
them with ZLIB/ZIP takes 29 seconds.

Generating 85 reports, discarding any existing ZIP files, and ZIPping
them by QSHELLing out to JAR takes 159 seconds.

Generating 85 reports, and using JAR to refresh them into existing ZIP
files by QSHELLing out to JAR takes 210 seconds.

The version of zip that I have allows what I expect should be a
standard zip command line feature. You can extract a single file from
the zip archive using the unzip command and also update the archive
with a new version of a single file using the zip command with the
update switch.

Obviously it's not the version of the ZIP CL command that comes in ZLIB, or at least in the ZLIB port we have. What is it?
