See my last post. I've used assembler, I've even hand-assembled.

LOL. That reminds me of the days I used to load a primitive boot
sequence into a PDP (DEC) by the switches in the front, so it could load
the next phase of the boot loader through the paper tape reader. I knew
the BINARY values of most of the instructions by heart. Those were the
days! The machine had core memory also. Not enough of it tho!

Obviously you've never used assembler. You guys are talking past each

talking about. (I think he's being a bit pedantic but...).

You simply don't know of which you speak. The 5% is the API interface
and a few other bits necessary for platform differences (CHanges in
the VM code to handle x86's incredibly wonky memory architecture,
etc). The 95% is what does the actual work, all the backend code for
EVERYTHING PS does, the plugin architecture and even as much of the
UI code as they can make common (there will always be some). PS maxes
at 2GB memory allocation on both Windows and Mac, this is due to
being a 32bit program and being designed for the common 2GB/2Gb split
that Windows and Mac prefer (Linux often uses a 1GB/3GB split, but
that's a kernel compile option and varies between system).

the user interface.
Yep, in Unix (Mac x) and XP that means the API. Modern
multiuser/multitasking OS do not properly allow direct access to the
hardware. Nothing I said was incorrect to anyone who understands
this stuff. What we are talking about is how the hardware reacts to
the software. For example PS uses 2 gigabytes max ram in Windows
(even if your system is maxed out with 16 or 32 gigabytes, and
whatever the kernel will allow it in Unix (that can be changed
simply in Unix, but not I think in windows).
And specifically, I do not know exactly how much is common code
between the two platforms. I do not even know what PS is coded in.
The programming language can make more difference than the hardware
does. I figured we were using educated guesses.
I get the feeling I am talking with school kids here (lots of facts,
not much understanding).
