Dear community,
I am a student, and I'm working on a little slots game (if the same random number comes up 3 timed, you win). I use Borland Pascal 7. I use graph to make this a bit more visual, but when I start the game my background turns from black to grey, and the other problem is that if I click the game start button, the game runs many times until I release the mouse button. How can I solve this? Here is my full program:
program slots;
uses mymouse,graph,crt;
var gdriver,gmode,coin:integer;
    m:mouserec;
    a,b,c,coins:string;
   procedure gomb(x1,y1,x2,y2:integer;szoveg:string);
   var j,n:integer;
   begin
      setcolor(blue);
      rectangle(x1,y1,x2,y2);
      setfillstyle(1,blue);
      floodfill(x1+2,y1+2,blue);
      setcolor(0);
      outtextxy((x1+x2)div 2 -textwidth(szoveg) div 2 ,(y1+y2) div 2-textheight(szoveg) div 2,szoveg);
      end;
procedure randomal(var a,b,c:string);
  begin
randomize;
  STR(random(2)+1,a);
  STR(random(2)+1,b);
  STR(random(2)+1,c);
  end;
procedure menu;
  begin;
   settextstyle(0,0,1);
   outtextxy(20,10,'Meno menu');
   gomb(20,20,90,50,'Teglalap');
   gomb(20,60,90,90,'Inditas');
   gomb(20,100,90,130,'Harmadik');
   gomb(20,140,90,170,'Negyedik');
   end;
  procedure teglalap(x1,x2,y1,y2,tinta:integer);
  begin
  setcolor(tinta);
  rectangle(x1,x2,y1,y2);
  end;
procedure jatek(var a,b,c:string;var coin:integer;coins:string);
  begin;
  clrscr;
  menu;
  randomal(a,b,c);
  if ((a=b) AND (b=c)) then coin:=coin+1 else coin:=coin-1;
  settextstyle(0,0,3);
  setbkcolor(black);
  outtextxy(200,20,a);
  outtextxy(240,20,b);
  outtextxy(280,20,c);
  STR(coin,coins);
  outtextxy(400,400,coins);
  end;
procedure eger;
  begin;
  mouseinit;
  mouseon;
  menu;
  repeat
  getmouse(m);
  if (m.left) and (m.x20) ANd (m.x<90) and (m.y20) and (m.y<50) then teglalap(90,90,300,300,blue);
  if (m.left) and (m.x20) AND (m.x<90) and (m.y60) and (m.y<90) then jatek(a,b,c,coin,coins);
until ((m.left) and (m.x20) ANd (m.x<140) and (m.y140) and (m.y<170));
end;
 begin
   coin:=50;
   gdriver:=detect;
   initgraph(gdriver, gmode, '');
   eger;
end.
Thank you very much,
Robert
