Robert, wouldn't you above example, not generate 1) the four bytes needed to
store the value *and* 2) the fourthy two bytes to store the code that
calculates the constant.

I mean:

constant my_string = "Hello, world"

Is in the code, in the memory of the interpreter, even before it is
executed.
Therefor it is in memory twice, unlike information loaded from a resource
file.

Really ? I can remember all kinds of 'program does not fit in memory' errors
on my old 286.
Trying to free-up conventional memory, unloading device drivers, etc.
It were not errors generated by the program I believe, rather by the OS.

I trust your word though, it does suprises me. Is the executable information
load-on-demand ?
Which would almost appear as if the OS is interpreting the executable file,
rather than the chipset, which was my guess.
