Because a property hides the implementation details ... you can change
to read / write methods later with no change to the code that is using
the property. A public field exposes the implementation.

I don't see the point in doing that, unless the read/write are
functions or procedures. Just make the string public.

Or as field properties if you want to access them from another form ...
type
TWallaceForm = class(TForm)
btnOK: TButton;
private
FWallacesPrivateVar: string; // private storage
public
property WallacesPrivateVar: string read FWallacesPrivateVar
write FWallacesPrivateVar;
...
end;

Probably as a field on the form class that you're dealing with.

FWallacesPrivateVar: string; // use this instead of your

Hope I've understood what you're asking for correctly.

Is there a way to store variables so I can use them from one procedure
to another?
I have been currently storing them in hidden edit.text boxes on the
form but there must be a better way.
