Hi,
   I want to write a unit which just contains procedures which can be used by the Main unit. I've tried doing this, but I don't know how to write a definition file for it. It doesn't contain any objects or attributes, just a list of procedures. Can anyone tell me how to do this?
Cheers.

Where should the code of the procedures resist ? In an external DLL or in the definition file ?
The interface part of any unit is a kind of definition file. It defines the interfaces of the unit. The implementation part contains the code of the interfaces or their adress in external libraries.
e.g.

// to be MyProcs.pas
unit MyProcs

interface

function TimesTwo(AValue : Integer): Integer;

implementation

function TimesTwo(AValue : Integer): Integer;
begin
  Result := AValue * 2;
end;

end.
// **

Just put MyProcs.pas in your link path, include MyProcs into the uses clause of the main unit and that's it.
