A negative char means counting from the end, so char -3 means the third char from the end. 2. Len is short for 'length", or the total number of chars in the string. 3. The above means put character starting at the total length of the string less 3, up to character the total length of the string into myExtension... Or put the last 3 characters of the string into myExtension. My guess is that the syntax is designed to demonstrate the length function rather than optimise the task. A simpler version of the example above would be: put char -3 to -1 of it into myExtension
