Report extracting data in FSUIPC Support Pete Dowson Modules Posted October 24, 2005 Mike I have developed and published an application that may be able to help you here. You should be able to get it from http://www.schiratti.com/starkie. It is a programming environment based on a subset of C, with extensions that allow you to define FSUIPC variables. e.g. You define a variable such as "int altitude at $4000", taking the figures from Pete's documentation. It will generate diagnostic output that you can control using printf. The output goes to a tabbed page in the same program. If you have any questions, please post an answer to this board. p.s. I have been working on enhancements to this program, but have been busy at work. The (as yet unreleased) new version supports plug-in DLLs. I will include a few DLLs before releasing, and tidy up the user interface.
