catia,
Thanks...I only worked with the C++ part of the Smiths and Honeywell boxes, and only in a few areas such as the WGS84 database/lookup, great circle calcs, and some at/above issues. Some of the NDB extended features were causing internal issues as well.
I understand that it works on top of VxWorks, but I thought that VxWorks was on the order of a machine language...
I was never sure if the C++ part was complied into something else...but that C++ was much easier to work with (and find programmers for), than the other languages.
Thanks for the clarification.
