 Unfortunatly, Leonardo did not post a complete example but this is what
 I get by guessing the missing parts.

He did on IRC. Note that the error is different depending on  = class; or =
class(tcollectionitem);

I used 2.5.1 (week old) tho.

unit quote;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils;

type
  TQuote = class;  // (TCollectionItem);  // change thise for a different
error

  TOnSqueeze = procedure (AQuote: TQuote); of object;

  { TQuote }

  TQuote = class(TCollectionItem)
  private
FAdjClose: Double;
FBBand_Diff: Double;
FBBand_Lower: Double;
FBBand_Middle: Double;
FBBand_Upper: Double;
FClose: Double;
end;

implementation

end.

 Hi, I'm trying to create a forward
 declaration for a class, as I use to do in Delphi, but I'm
 getting Forward type not resolved. How can I troubleshoot
 this?.
 
 Here's the code:
 
 {$mode objfpc}{$H+}
 
 interface
 
 uses
   Classes, SysUtils; 
 
 type
   TQuote = class; // forward declaration.
 
   TOnSqueeze = procedure (AQuote: TQuote); of object;
 
   { TQuote }
 
   TQuote = class(TCollectionItem)
   private
     FAdjClose: Double;
     FBBand_Diff: Double;
   ...
 
 And, this is the error I'm getting:
 
 quote.pas(11,12) Error: Forward type not resolved TQuote
 

Sorry, the error was here:

   TOnSqueeze = procedure (AQuote: TQuote); of object;

This line should be:

   TOnSqueeze = procedure (AQuote: TQuote) of object;

amazing what a misplaced semi-colon will do, eh? ;)

i would have thought that there would have been an additional error concerning 
the trailing of object... was there? did it give a clue as to the actual error 
of the misplaced semi-colon?

im still trying to understand how the compiler understood that
sentence in order to generate THAT specific error... (while ignoring a
totally out of place 'of' token)
