I can remember that “[000000...]” was a valid directory wildcard spec, but 
“[0,0...]” was not.

Also remember “<” ... “>” was valid for directories, and a dot instead of 
semicolon for file versions, à la TOPS-10.

Is it called inetd on VMS?

I can remember various “inetd” and “xinetd” servers, depending on the 
flavour of *nix. Nowadays systemd offers a more modular way of managing 
things.

From VMS days, I vaguely remember those numbers you had to specify for 
DECnet connections, e.g. “23=” for a remote terminal connection, “0=” or 
“task=” for running your own arbitrary remote command, something else for 
FAL (remote file access) etc. Other systems soon settled on the idea of 
server processes listening for connections on particular ports (e.g. file 
servers), but for some reason DEC never cottoned on to that concept.
