I suppose this is because I'm assigning a larger string
to an array[] of char that cannot hold it.  Strange, even
with runtime range checking on, fpc doesn't catch this
problem.  dcc apparently does as early as compile time...
or am I missing something here?

Also, will the writing outside of array bounds in lines 16
and 17 corrupt memory even with runtime range checking on?
With RRC off, I'm almost sure it will, correct?
