how to write and read array record into file??

[amazing_grace]

hi,

i am working on a project to write data into the file and use a search enginee to get the data back. i was advised to use record but i didnt learn record at school. i tried to google it but came up with no solution. that's so far i got but there are a tons of errors:

type
data=record
name:string;
tel:string;
end;

var
infor:array[1..2] of data;
f,a:file of data;
begin

[here i assign some information to the record arrays]

assign(f,'file.txt');
rewrite(f);
writeln(f, infor[1]);
writeln(f, infor[2]);
[ i try to write the records into the file]
[ here is where i got the errors]

assign(a,'file.txt');
reset(a);
i:=1;
while not eof(a) do begin
readln(a, infor);
i:=i+1;
end;
writeln(infor[1].name);
writeln(infor[2].name);
[ i try to read the record back from file and display them on screen. but i never know if it works]

Please, i need your help!!! i am not sure if there is 'record array' and how to write or read' record array' into or out of the flie. please help me!!

I'll try to explain everything...

Program Solution;

Uses Crt;

type data=record
            name:string;
            tel :string;
          end;
var
   infor:array[1..2] of data;
   F:file of data;
   i:Byte;{our little helper...}


Begin  {the main program}
     ClrScr;
     {
     here you assign the file's variable to the file.
     Remember that the 'file' word is reserved word!
     }
     Assign(F,'Yourfile.dat');
     {
     Ok.Now we want to create this file,or if it is exists then
     delete its contents!
     }
     Rewrite(F);
     {
     now we want to write to this file 2 records..
     let's see...
     }
     i:=1;
     WriteLn(i,'.Name: ');
     ReadLn(infor[1].name);{ok,we get the first field of the first record}
     WriteLn('Her/his phone: ');
     ReadLn(infor[1].tel);{and the phone too}
     Inc(i);
     WriteLn(i,'.Name: ');
     ReadLn(infor[2].name);{ and we get the first field of the second record}
     WriteLn('Her/his phone: ');
     ReadLn(infor[2].tel);{and the phone too}
     {
     ok,our array is filled by the user
     }
     WriteLn;{just an empty line...}

     {
     now we want to write this data to that file,assigned by F
     we use the 'for loop' to write the data,so we do not need
     to increase the value of 'i'.
     }
     For i:=1 To 2 Do{'cause our array has two elements(records)}
     Begin
        Write(F,infor[i]);{do you see???}
     End;{of for loop}
     {
     ok,now our array is written to the file!
     now we try to read it back
     }
     {
     but first we close this file..
     }
     Close(F);
     {
     opening for reading...
     }
     Reset(F);
     {
     we read the data back,and write to the screen...
     }
     i:=1;
     While Not (EoF(F)) Do
     Begin
        Read(F,infor[i]);
        Write(i,'.Name: ',infor[i].name,'  Tel: ',infor[i].tel);
        WriteLn;
        Inc(i);{same as i:=i+1}
     End;{of while}
     {
     and last,we close the file again...
     }
     Close(F);

     ReadLn;
End. {end of main program}
