Subject: Problem with a list in Pascal?

I would be very grateful if someone could help me out with this one.
I've a program were the user should put in data about dogs, and then be able to write them out on the screen.

PROGRAM inlu5(Input, Output);
TYPE String_15=packed ARRAY[1..15] of CHAR;

hundpekare =^hundtyp;

hundtyp=record
namn : String_15;
ras : String_15;
age : Integer;
vikt : Integer;
next : hundpekare;
END;


VAR first,ny,temp : hundpekare;
continue : Boolean;
kom : Char;
i,antal : Integer;

BEGIN
Writeln('Welcome to dogprogram!');

new(first);
first^.next:=NIL; {pekaren nollställs}
Write('Name of dog?'); Readln(first^.namn);
Write('Race of dog?'); Readln(first^.ras);
Write('Age of dog?');Readln(first^.age);
Write('Weight of dog?'); Readln(first^.vikt);

continue:=true;
Repeat
BEGIN
Write('Do you want to put in data about another dog?Y/N');
Readln(kom);
CASE kom OF
'Y','y': BEGIN

new(temp);
temp:=first;
Writeln(first^.namn:5,':',first^.ras:5,':',first^.age:2,' first^.'); Writeln(temp^.namn:5,':',temp^.ras:5,':',temp^.age:2,' temp^.');

repeat
BEGIN
Writeln('Loop!');
temp:=temp^.next;
END;
until (temp^.next=NIL);

Write('Name?'); Readln(temp^.next^.namn);
Write('Race?'); Readln(temp^.next^.ras);
Write('Age?');Readln(temp^.next^.age);
Write('Weight?'); Readln(temp^.next^.vikt);
temp:=NIL;
END;
'N','n': continue:=false;
Otherwise
BEGIN
Writeln('Wrong kommando, try again!');
continue:=true;
END;
END;
END;
Until NOT continue;

Writeln(antal);
Write('Do you want to write the register? Y/N:');
Readln(kom);
Case kom of
'Y','y': BEGIN
{ I dont know how to make this correct}
END;
'N','n': Writeln('Bye');
Otherwise Writeln('Wrong kommando. Bye!');
END;
END.
