Conditional statement the possible of use:

if i > 10 then

Other pieces of example codes:

while i>0 do
   if i=10 then
     break
   else 
   begin
     dec(i)
   end;

if  x >= 12 then
   while  y >= 0 do  
      dec(y);

if y<5 then
   y := y/ 3.14;    // y = 1.234

if x > 0 then // x == true
   x:=5;

if x>$abc then
  y := x / $a;    // y = 466

if x>10 then
  y := x / $a;   // y = 1
