OK, I reply to myself. I just found a similar example and this is the result :

#import <Foundation/Foundation.h>

@interface Person : NSObject
  {
    NSString *person;
  }
  -(void) SetPersonName : (NSString*) name;
  //-(NSString) GetPersonName;
@end

@implementation Person
  -(void) SetPersonName : (NSString*) name;
    {
      [name retain];
      //[person release]
      person = name;
    }  
@end

int main (int argc, const char * argv[])
  {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    Person * testperson;
    testperson = [Person alloc];
    testperson = [testperson init];

    NSString * nametogive = @"Louis Armstrong";
    [testperson SetPersonName : nametogive];
    [pool drain];
    return 0;
  }

Somehow I don't get any error, I have to verify if it actually prints "Louis Armstrong". I'll let you know. One question. I don't get this passage:

-(void) SetPersonName : (NSString*) name;
    {
      [name retain];
      //[person release]
      person = name;
    }

What is the "retain" doing ?

Thanks
