CV

A character-type argument that returns the version
number.

Notes
(a)
The version number refers to the terminal part of the bus name for the file
system which stores the library. (For example, dcl-5.0 in /usr/local/src/dcl-5.0).
However, the character string that is actually returned is system dependent,
although the character string will never be an empty one.
