The substr function will return parts of a string, and may also be used to replace parts of a string. The concatenation operator (.) may be used to add characters to the end of the string. The index function will return the first position of a substring within a specified string, and -1 if the substring cannot be found. The rindex function returns the last position, so you can use it to find the last space in a string. > > Is that a tall order? I'm hoping it's trivial for someone here. It should be straight-forward to put these functions together to do what you want. Give it a try and come back here if you can't get it to work.
