I was misled by a typo in the man page for file, where it says:
Under Windows, 'file' can also be used with 'description =
"clipboard"' in mode '"w"' and '"w"' only.
Presumably that should be "in modes '"r"' and '"w"'."
In the ?load page, I see the words "suitable connection", but I don't
see any mention of binary access being required. Is that documented
somewhere?
I guess it comes from the use of gzcon in load. Couldn't the
restriction be removed by having gzcon treat any text mode connection
as uncompressed?
