I am currently making a generator that generates rewards (simulation). How would I make it pick a random variable?

Like pick a random one of these:

Bpartyhat,Wpartyhat,Gpartyhat,Rpartyhat,Ypartyhat,Ppartyhat,boxopened:integer; //6
pernixcowl,pernixtop,pernixlegs,virtushood,virtustop,virtuslegs,Crapier:integer; //7
Cmaul,Cstaff,Bmelee,Brange,Bprayer,Bmage,Bagility,Btheiving,Bhuntig,Bmining:integer; //10
Bsmithing,Bfishing,Bcooking,Bfiremaking,Bwoodcut,Dchain,Dlegs:integer

I am currently making a generator that generates rewards (simulation). How would I make it pick a random variable?

Like pick a random one of these:

Bsmithing,Bfishing,Bcooking,Bfiremaking,Bwoodcut,Dchain,Dlegs:integer

    case Random(4) of
      1: Bpartyhat;
      2: Wpartyhat;
      3: Rpartyhat;
      4: Ypartyhat;
// and so on
    end; 

Exactly how I would have done it^^^. Just make the case statement bigger, fill it with everything, and add a larger random to fit it.

Its even more fun if you add a case statement in a case statement!

So what would be the id statement for this

if pick 1 then begin
code here
end;

Can even do it a different way like this

program new;

var
Items: TStringArray;

procedure DeclareItems;
begin
  SetArrayLength(Items,10) //set how many items we have including 0 (we have 10 currently)
  Items[0] := 'Bpartyhat';
  Items[1] := 'Wpartyhat';
  Items[2] := 'Gpartyhat';
  Items[3] := 'Rpartyhat';
  Items[4] := 'Ypartyhat';
  Items[5] := 'Ppartyhat';
  Items[6] := 'Bsmithing';
  Items[7] := 'Bfishing';
  Items[8] := 'Bcooking';
  Items[9] := 'Bfiremaking';
end;

function PickRandomItems(Amount: Integer): String;
var
i : integer;
begin
  Writeln('Our '+ ToStr(Amount) +' items are:');
  Result := '';
  for i := 1 to Amount do
  Result := Result + Items[Random(Length(Items))]+', ';
end;

begin
DeclareItems;
writeln(PickRandomItems(3));
end. 

Our 3 items are:
Bsmithing, Ppartyhat, Rpartyhat,
