How do they differ? "ls" returns a simple list of filenames in both.
"ls -l" returns; file modes, number of links, owner, group, filesize,
last modified time and filename. While beyond that they offer different
options these are the only two generic to a discussion of what FTP
returns. And, while most (all?) unix systems use the ls command and
pipe the output thru the FTP server it seems it would have been rather
trivial for VMS to read the directory and send the information in a
similar (and compatable) format. Whyh they don't is not information
I am privy to.

This then starts to look like the C headers, and all the conditional logic that builds up in such as the targets move.

And as for mapping OpenVMS names into Unix names (or the other way 'round), there are a gazillion obvious filename translations, and some really ugly ones. What's ., after all? The corner cases are enough to drive any sane engineer up the wall.

The only way I can see to reasonably engineer this within TCP/IP Services likely involves a sniff of the client, and add a flag that resets the output to look like Unix. (This so we don't bust existing clients that expect existing formats.) But I've seen cases where this won't work, because the client sniffs the server, and reacts differently depending on what it finds. Which leads to ever-lengthening stacks of hackery, and more control knobs, and more misleading responses when you ask for identification, and pretty soon you end up with.... SCSI! :-)

Alternatively, to update the FTP RFC to add a new FTP sequence with a defined format for the filenames and directory names, and to wait for everybody to agree to it and to decide to implement and ship it.

Yes, I'd like to see a way for Microsoft and TCP/IP Services to play together better here, but then I also gave up on Internet Explorer and have been using Mozilla Firefox for eons now. I do need to test-drive the newest IE7 stuff, to see how much that has improved.
