The compilers I have used call CARDINAL() a function;  they then get difficult
about not allowing assignments to function values.  I spent a long time chasing
this one down.  

A similar one that bits me is:
  VAR v1 : recPtr;
  ...
           recPtr( cardinalvariable ) ^ := expression
I still don't know why I can't dereference a pointer function type, but it  
seems to be forbidden.
