No, "pip" is a file manipulation program, which -- depending on OS -- provides
as command options the analog of Unix commands cat, cp, mv, ls, etc.
If you mean "dd" as a partial file copying program, that's something I haven't
seen on DEC OSs. For image copying (non-file-structured copying), it may be
that pip can do that but often it won't because it only does file structured
operations in many systems. On VMS (and some other systems) there may be
something like "copy/image" which may work. Support for raw block access of
file devices varies, though; it depends on whether the OS allows such a thing.
To pick one example, RSTS originally did not allow that; it was added part way
through the OS history.
