How to call procedure (or function) that is placed
(defined) in another Unit?

Commented:
I suppose you're familiar with the "uses" statement so:

unit main;
   .
uses Unit1...
   .
   .
procedure MyProc(Param: Integer);
begin
   .
   .
end;
   .
   .
..TMainForm.Create...
  Unit1.ExtProc := MyProc; // Copy function pointer
   .
   .
end.  

------------------------------------

unit Unit1;
   .
   .
var
  ExtProc: procedure (Param: Integer);
   .
   .
  ExtProc(123); // Calls procedure from "Main"
end.
