hello !!
I wonder if this book can be sheeped for people in north africa ?
books about deep object pascal understanding are very few and if they exists they traite more Delphi;
like :
http://www.marcocantu.com/objectpascalhandbook/, So I suggest if you can write a similar printed book on object pascal ( advenced ) for lazarus/FPC typically.
I'll be very happy to contribute .
thanks
PS; can't find the URL of the 2nd edition of the book; lazarus the complete guide.
