V

varying array
In RPC, an array whose range of transmitted elements is determined at run time by another parameter, structure field, or expression. See also conformant array and open array.
version number
In RPC, two numbers, separated by a decimal point, that identify the version of an interface. To be compatible, the major version number (the number to the left of the decimal point) must be the same for both client and server, and the minor version number of the server must be greater than or equal to the minor version number of the client.
