1. A system usable with a wellbore, comprising:
- a plurality of flow control devices deployed in the wellbore, each of the flow control devices having a plurality of states;
a hydraulic control line; and
a plurality of indexers, each of the indexers being in fluid communication with the hydraulic control line and being functionally connected to a different one of the flow control devices;
wherein the indexers are configured to operate in concert in response to pressure in the hydraulic control line to select each of at least three different permutations of the states.

Abstract
The invention is a system and method a system used to control multiple downhole tools with one control line. The downhole tools may comprise any hydraulically actuated tools, such as valves, packers, or perforating guns. Each tool is associated with an indexer, in one embodiment, so that the tools can be operated in concert and as a system.
