Break-statement in TP 5.5

Hi experts
i'm using TB 5.5 (free pascal)
the problem is;
i need to write a function who compares two arrays of 4 shortint to see if 2 numbers are the same
take for example those 2 arrays
1 2 3 4
2 2 2 8

i wrote this code

FUNCTION Case1:Boolean;
Var Temp, i, j:ShortInt;
Begin
Temp:=0;
FOR i:=1 TO 4 DO
 FOR j:=1 TO 4 DO
  IF Digit[i]=Guess[j] THEN
   Temp:=Temp+1;
IF Temp>=2 THEN Case1:=TRUE;
IF Temp<2 THEN Case1:=FALSE;
End;

the problem is that because there are in the second array more than one '2' the output = TRUE but that shouldn't be
because there is only 1 number in the two arrays who are the same

i thaught i could use the BREAK-statement like this

FUNCTION Case1:Boolean;
Var Temp, i, j:ShortInt;
Begin
Temp:=0;
FOR i:=1 TO 4 DO
 FOR j:=1 TO 4 DO
  IF Digit[i]=Guess[j] THEN
   begin
   Temp:=Temp+1;
   BREAK;
   end;
IF Temp>=2 THEN Case1:=TRUE;
IF Temp<2 THEN Case1:=FALSE;
End;

from an algoritmic point of view that should be good I THINK
but the BREAK statement (which is used to abort the actual loop) doesn't work in TP 5.5
could someone help me out ???
 thanks in advance

or maybe you can just give me a way to go out or to skip the current loop
an alternative to the BREAK statement

SORRY EVERYONE
i found the answe myself
to "break" a while loop i did

FOR i:=1 TO 10 DO
 Begin
 WriteLn(i);
 IF i=5 THEN i:=10;
 End;

The Output is
1
2
3
4
5

sorry

Doesn't matter. However, personally I consider the use of the Break statement something that you should avoid at all costs. Like the Goto statement and some other statements the Break statement makes the source a bit less readable.
Instead of a for-next loop you could also use a While-Do loop like this:

var
  I:Integer;
  EndOfLoop: Boolean;
begin
  I := 0;
  EndOfLoop := False;
  while (I < 10) and not EndOfLoop do begin
    I := I + 1;
    WriteLn(I);
    if (I=5) then begin
      EndOfLoop := True;
    end else begin
      // Perhaps do some other code.
    end;
  end;
end;
