dcblogs writes: An OpenVMS user group in France has posted an "open letter" to Hewlett-Packard CEO Meg Whitman urging her to reconsider HP's decision to begin pulling support for the operating system. The letter, written by OpenVMS consultant Gerard Calliet on behalf of user group HP-Interex France, explains the important role OpenVMS plays in running transportation systems, health services and even nuclear power plants in France. "These software products are the result of decades of precise programming, inscribed in precise coding imperative for such functional necessities," Calliet wrote. "A majority of them use functions specific to OpenVMS and still run on OpenVMS, as these custom features are hard to find elsewhere." The user group accuses HP of being unclear about its direction and creating confusion. In 2013, HP said it would not be validating OpenVMS on its latest Itanium-based systems.
