Please look at the following code

{-------------------------------------}
PROGRAM bank;

USES wincrt;

TYPE num= ARRAY[1..10] OF integer;
     money= ARRAY[1..10] OF real;
VAR
 data:text;
 numbers:num;
 search:boolean;
 i,wrong,right,n,id:integer;
 money1:money;

PROCEDURE loadata(VAR number:num; VAR moneys:money);
 VAR i:integer;
 BEGIN
  FOR i:=1 TO 10 DO
  readln(data,number[i],moneys[i]);
 END;

PROCEDURE dosearch(number2:num; VAR n2,numm:integer; VAR search2:boolean);
 VAR i:integer;

 BEGIN
  writeln('Please enter your ID numbers');
  read(numm);
  FOR i:=1 TO 10 DO
   IF numm=number2[i] THEN
    BEGIN
    search2:=true;
    n:=i
    END
 END;

PROCEDURE output(number3:num; moneys2:money; search3:boolean; VAR wrong2,right2:integer);
 BEGIN
  IF search3=true THEN
   BEGIN  
   writeln('Your ID numbers is ',number3[n]);
   writeln('You have $ ',moneys2[n]:1:2);
   right2:=right2+1;
   END
  ELSE
   BEGIN
   writeln('This ID is invalid');
   wrong2:=wrong2+1;
   END
 END;

BEGIN
 wrong:=0;
 right:=0;
 REPEAT;
 assign(data,'c:\tpw\account.inf');
 reset(data);
 loadata(numbers,money1);
 dosearch(numbers,n,id,search);
 output(numbers,money1,search,wrong,right);
 UNTIL id=9999;
  BEGIN
  writeln('Thanks for using me');
  writeln('You entered ',wrong,' invalid ID numbers and ',right,' valid ID numbers');
  writeln('Here is the information');
  writeln('ID#       BALANCE');    
   FOR i:=1 TO 10 DO
   writeln(numbers[i],'       ',money1[i]:1:2);
  END;
END.
{-------------------------------------------}
and here is the data
{------------------------------------------}
1357    33.50   Flo Chart
6666    150.33  Hedda Hare
3312    226.97  Holly Wud
1020    0.0     Sue Err
8282    78.77   Otto Mobile
2200    924.75  Howard Countee
1234    8000.00 Jim Sox
1313    1.00    Adam Upp
7971    0.0     Barney Ard
7894    445.12  Debihi
{------------------------------------------}
The program is work fine, but if enter a invalid number after a valid number then it will output the info for the last valid number
And it's always a one more value to what ever number you enter..doesn't matter it valid or invalid.
