Beginning Pascal

My assignment is to write a program that does the following:
Ask the user how many bills they are entering for calculation?
Have the user enter as many as 8 bills (the amount of each bill)
then add all the bills to get a total then get the average.
I understand how to get the total and average.
I also can get the user to enter how many bills they want to enter.
this is what I have so far --
begin

      writeln('How many bills will you be entering today?');
      readln(billnum);
      if billnum  <9 then
      else writeln('The system can calculate as many as 8 bills at a time.  Please enter 8 or less bills');
         readln;

end.

Can anyone help with creating a loop that will allow the user to enter the amounts of each bill???

Thanks a million !!!

Okay, this isn't too hard. (But technically, I have to mention the EE is NOT for homework assignments...)
____________________________________

Uses SysUtils;

Var
  Counter,Total:Integer;
  Input:String;

Begin
{ ... Your code goes here ... }
  Total:=0;
  For Counter:=1 To Billnum Do
  Begin
    Write('Please enter bill #',Counter,':');
    ReadLn(Input);
    Total:=Total+StrToInt(Input);
  End;
  WriteLn('Total is ',Total);
  WriteLn('Average is ',Total / Billnum);
End;

Actually, you can read the input directly as an integer (Given you use integers for your bills, if you want to use floating point numbers you have to use "Real"s), then you don't have to use StrToInt();

Success!

Thanks nrico,
This information was very helpful.  In the past I have used EE to help me with my home work assignments.  I really don't expect people to give me the answers, but people have pointed me to web sites that have the information I am looking for and that has been very helpful.
Thanks again !!
