Doesn't make much sense to me at least.Who still codes in 16 bit or turbo pascal ? 64 KB programs ? Terrible limitations. I am glad those days are dead/gone/over.
If you want Delphi mode, you just put
{$Mode Delphi}
at the beginning of your unit, among the other compiler switches (if any).
If you don't, you get the default fpc mode, which requires a stricter
syntax.
type TPenis = class // accepted in Delphi mode is a shortcut for type TPenis = class(TObject) // required in fpc modeIn both cases TPenis is a descendant of TObject, but in Delphi mode case you don't see it.
From Delphi manual page: <begin quote>If the declaration of a class type doesn't specify an ancestor, the class inherits directly from TObject. Thus
type TMyClass = class ... end; is equivalent to type TMyClass = class(TObject) ... end; The latter form is recommended for readability. <end quote>So if you follow Delphi manuals recommendation, you don't see the difference, from 16 bits TP to 64 bit fpc. If you choose not to follow them, then you must specify that you want Delphi mode.
Another difference you'll find from fpc mode to Delphi mode is the implicit pointer accepted for constructs such as:
MyObjectOnClick := Button1Click; // accepted in Delphi mode as opposed to: MyObjectOnClick := @Button1Click; // required in fpc mode I'd suggest you to read the wiki pages from Mattias reply.
