Do you really need pointer arithmetic, null terminated strings and array downgrade to pointers for real work?
Because every other language in the planet is able to deliver real work without them. Even the ones that existed before C.
Skype was originally created in Delphi, before being ported to Qt.

Pixel32 is done with FreePascal http://www.kanzelsberger.com/ http://en.wikipedia.org/wiki/Pixel_Studio_Pro
Atmel AVR-Microcontrollers programmed in Pascal http://www.e-lab.de/index_en.html http://www.mikroe.com/eng/categories/view/2/compilers/
Should I keep posting examples?
Or for you is Pascal only the very first release of the standard, which was only planned for education purposes?
Most of other examples are about a thin layer of Pascal on top of (unsafe and non kosher) C.
Of course you have to write on top of C, because that is what, sadly most operating systems are still written today.
But even that is slowly changing, when we look at the way operating system development is evolving, with safe layers on mini kernels, like Google is doing with Android or Microsoft with WP/WindowsRT/Singularity.
Anyway, I am stopping here, as won't convince you of anything and you won't convince me.
