[DUG]: Newbie questions about scope

[Mark Howard]

1. I have started going through my app and removing from the Interface sections of each unit any declarations that are not referenced by other units.   Apart from "good programming practice" are there any real benefits in doin this?   2. Where a procedure of function is used only within one other procedure in a unit there are two choices - either   procedure aaa: begin     do stuff end;   procedure bbb; begin     procedure aaa;     other stuff end;   OR   procedure bbb;   procedure aaa: begin     do stuff end;   begin     procedure aaa;     other stuff end;   Are there any real differences between the two? and if so what are they?   TIA   Mark
