Can anyone think of a situation in which you would *have* to use
forward declared functions? I'm trying to come up with an example for
such for my book, and I am drawing a blank.
Well, maybe this one:
-------------------------------------------------------------------
type SorterProcType = function (String1,String2 : shortstring) :
boolean;
function CompareIt1(String1,String2 : shortstring) : boolean; forward;
function CompareIt2(String1,String2 : shortstring) : boolean; forward;
function CompareIt3(String1,String2 : shortstring) : boolean; forward;
const SortCriteria : SortProcType = CompareIt1;
-------------------------------------------------------------------
I don't know of another way that you can use one of the "CompareIt1/2/3"
functions in the const declaration for "SortCriteria" (but maybe there
is one).
