This is a little misleading. The PRC contains, in addition to the
program code, the initial data for initialized global variables. Since
your global array was uninitialized, the system can mark it as such,
and zero-fill it when the app starts. This avoids the storage of
100*sizeof(structure) bytes in the PRC. If your array had been
initialized with non-zero data, then it would have taken up noticable
space.
It's roughly analagous to data vs. bss segments in traditional desktop
applications, although the PRC format is a bit weirder.
