Re: lost in gnustep first steps

@interface Dico: NSObject
{
NSMutableString *egy;
}
+ (id) new;
- (void) setEgy: one;
@end
   

- (id) init
{
 if( (self = [super init]) )
 {
   egy = @"";
May I point out that even though the instance variable is declared to 
hold a mutable string, that this assignent actually sets it to an 
NSString.  The compiler should have warned about this also.  To get a 
mutable string you should try:
egy = [NSMutableString new];

void main(void)
{
 NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
 Dico *szotar = [[Dico alloc] init];
 [szotar setEgy: @"nagzo ddf"];

and either [szotar setEgy: [NSMutableString stringWithString: @"nagro 
ddf"]];
or [szotar addEgy: @"nagro ddf"];
and implement
- (void)addEgy:(NSString *)addition
{
 [egy appendString: addition];
}

On the other hand, I must also admit that your code samples didn't seem 
to reflect your stated intentions, and that Pascal's reply seems better 
focused at your expressed intent.

May I suggest the following tutorial on some of the basic GNUstep 
classes, such as:
NSString / NSMutableString
NSArray / NSMutableArray
NSDictionary / NSMutableDictionary
