Dear Programmers

Could you please supply me with a piece of code in Pascal (Turbo 7) to answer the following problem:

Declare an array N which contains 30 cells of integer type and prompt the user to read in 30 integers between 0 and hundred.

Validity of input between 0 and 100 is important.

program FillArray;

  I: byte;
  N: array[1..30]of integer;
  Value: integer;

  writeln('This program fills an array of 30 elements with values between 0..100');
  for I := 1 to 30 do begin
    writeln('Enter a value (0..100) for element ', I, ' : ');
    until (Value >= 0) and (Value <= 100);

First of all thanks to eddiejr,   I was aware of the code but I wanted to be sure that I answered correctly.  This was my first time.  Next time I paste the code and ask for your comments.
