Copying directory trees under VMS.

I have recently found the time to start playing with my VAXen again, and have been struck by a bit of a confusing dilemma: Why is it that when I attempt to copy a large tree from any place to another under VMS 7.2, it always copies as follows: This command: backup dub3:[000000...]*.*;* dub2: causes vms to copy a directory structure that looks like this: [000000.000TOOLS.AXP]file1...file2...etc [000000.000TOOLS.VAX]file3...file4...etc to this: [000000.000TOOLS] (empty) [000000.AXP]file1...file2...etc [000000.VAX]file3...file4...etc How do I get it to copy the whole *tree* in a directory or on a disk to a whole other part of the system? I tried reading the help available on copy and backup, but I haven't been able to figure out how to copy a whole tree from one place to another. Thanks for your help! Greg Linder fluke(a)mcs.net
