Not really - they aren't anywhere, so you wouldn't be able to find them.
When your app isn't running (and when it is running but globals haven't
been created), there's no memory anywhere that stores those globals. The
whole point of not setting up the globals world was to save time and memory
on little launchcodes which hardly ever needed them.
Think of how the compiler does things: to access a global variable, it
takes register A5 and adds an offset, and uses that as the location of the
global variable. Now when globals are being set up, what this means is
that the system allocates a bunch of memory, initializes it, and points A5
to it. And then when your app quits, it frees that memory block. So when
you don't have globals available, it isn't that we're sadistically hiding
them; instead they simply don't exist!
And yes, this sort of thing will certainly change in newer OS releases.
