may z be placed in ROM? - Nope.
may it be changed? - Not by the language

I have actually seen a program using such a variable.  It was for a read
only register of a HW device.  You could read it, but not write to it (hence
the const).  OTOH the HW itself was changing this value all the time, so it
had to be volatile.  It does make sense.  But it was looooong time ago when
I have seen this.  DOS world, not even 6.2.

So I cannot call tourist class seats of long-haul flights a keyhole then.  I
have to stick with sardine-can.  :-)
