[pascal] problem z generowaniem grafu

witam na foum! [soczek]

pisze do Was - Specjalistow - z moim problemem:

napisalem program ktory nie chce dzialac tak jak powinien - nie losuje tylko wypisuje kolejno krawedzie.

temat to:
[i]Algorytm generowania grafu G = G(n, k) w tablicy E, procedura przepisania informacji do tablicy S, drukowanie z E i drukowanie z S, pomiar złożoności. [/i]

a to co napisalem:

[code]program projekt(input,output);
uses dos;
const nmax=100; kmax=nmax*(nmax-1) div 2;
type ind=1..nmax; ind1=1..kmax;
elem=1..nmax;
zbior=set of elem;
r=record a,b:integer; code:Boolean; end;
rs=record w:zbior; l:integer; end;
t=array[ind] of integer;
t1=array[ind1] of r; { E }
ts=array[ind] of rs; { S }
alfa=string[15];

end;

end; { init }

procedure Gnk(n,k,total:integer; var E:t1);
var i,l,z:integer; x:r;
begin
l:=total;
for i:=1 to k do
begin
z:=random(l) + 1;
x:=E[z]; E[z]:=E[l]; E[l]:=x;
l:=l - 1;
end;
end; { Gnk }

procedure transES(n,total:integer; var E:t1; var S:ts);
var i,h:integer;
begin
for i:=1 to n do with S[i] do begin w:=[]; l:=0; end;

    begin

    end;

end; { transES }

writeln('end? 0/1'); readln(key);
until key=1;
close(out)
end.[/code]

co jest nie tak ze nie losuje? help...:(

dziekuje za pomoc i serdecznie pozdrawiam :)
