pascal input number

To input a number in Pascal, you can use the ReadLn function. Here's an example:

program InputNumber;

var
  number: Integer;

begin
  Write('Enter a number: ');
  ReadLn(number);

  // Do something with the number

end.

In this example, the ReadLn function is used to read a number from the user. The number is stored in the variable number, which is declared as an Integer. The Write function is used to prompt the user to enter a number.

After the number is read, you can perform any desired operations or calculations with it.
