Hello,
I supposed that you mean `substring = string.sub( your_string, Start, End )`
We wil start with this:
your_string = "Hi Andrew!"
Let's take the substring starting at the first character and ending at
the fourth one, and put it in the `hi_initial` variable.
hi_initial = string.sub( your_string, 1, 4 ) --> Hi_initial is now "Hi A"
`your_string` has not been modified.
Now, we take the string that starts at the fourth letter and ending at
the second one starting from the end.
name = string.sub( your_string, 4, -2 ) --> name is now "Andrew"
This is equivalent: start at the sixth from the end and end at the
ninth from the start.
name = string.sub( your_string, -6, 9 ) --> name is now "Andrew"
I hope it helps.
