Just selected ones.

Thanks.  I dimly recall someone saying something about

const char *x;

vs

char * const x;

vs

const char * const x;

I don't know if the last 2 are legal (the dim recollection says
they are), but in future, I'll try to remember the common bit under
the rule "const applies to the closest thing!".  BFN.  Paul.
