pascal string length

To determine the length of a string in Pascal, you can use the Length function. Here's an example:

  myString: string;
  len: integer;
  myString := 'Hello, World!';
  len := Length(myString);
  writeln('The length of the string is: ', len);

In this example, the Length function is used to calculate the length of the myString variable. The result is then stored in the len variable, which is then printed to the console.

Please note that the Length function returns the number of characters in the string, not including any null-terminating characters.
