..... makes my little announcement and contribution seem rather feeble by comparison, but here goes

So, as promised, here's the first (beta) version of my CreditBOND Calculator ....
ScreenShot (running under Windows 10):

This is a
stand-alone executable (no installation). I can confirm that the file is free of viruses, but please don't take my word for it; do your own tests and/or run the exe in a sandbox.
Please check that my assumptions and calculations (regarding blocks and yields) are correct and please report any errors that you may find.
This is presently
Windows only (though it should run in a Windows emulator/VM on other platforms). If there is sufficient interest, I'll consider developing a cross-platform version next and maybe adding more features later such as local currency conversions. Feature suggestions welcome.
