Dear FPC-Developers!
Our institution about 15 years ago was developed Turbo-Vision fork for
VGA/SVGA graphics called GraphVision.
Key features:
* TV-like objects (classes)
* BGI graphics with own
There is a slightly more modern P5 based off of P4, with source code that can
be compiled using Borland Pascal (and presumably, FPC's Turbo mode should be
close to compiling it as well.)

Have you looked at target embedded ? For what specific platform are you
contemplating this for ? (i.e. what specific need is driving this question ?)
It implements a very minimal set of things, basically the minimum necessary to
support the language core, and the minimum necessary to support

I assume I speak for others, but for those of us that have been working in the
embedded field for a while, some of us prefer to roll our own support code,
rather than rely on compiler supplied implementations. Personnally, I've used
6
different ARM/Thumb2 cored processors in various projects.

Been playing with the ARM / Thumb2 part - specifically for the Thumb2 line-up.
The compiler proper can be built to switch between the two with a command line
switch. However, the RTL gets called as ARCH-SYSTEM, this only allows the
RTL to compiled for one or the other.
This may be by
.thumb_func
.globl _start
.text
_start:
you dont have to do this:
.long _start+1
you can do this instead:
.long _start
at least for gnu as, not sure if this code is targeted at different assemblers.

not the instruction set). And SYSTEM is either ARM (the instruction set) or
thumb2/cortex-m3? Am I understanding that so far? Or is ARCH ARM or
cortex-m3 and SYSTEM is stellaris, lpc21x4, etc?

One of my current fixes i have in place allows using the PPCCROSSARM compiler
to compile Pascal to Assembly. Once in Assembly, the files can be assembled
and
linked like any other program. So, you have the capability to do just about an
exotic configuration you want - you just have to do so
