[Tutor] split a 5 chars word into 4 and 1

Hello, I'm trying to split 5 chars words (codes) into 2 variables. The first must contain the first 4 characters. The second variable will only contain the last character. I'm working in a loop pre-generated codes. Any magic command for this ? :-) Examples of codes : 3cmvA 3cmvB 3cmvC 3cmwA 1g18
