play = menu("Play A Word Game? ","Yes","No");
cPLAY = 1;
while play == 0 && cPLAY < 5
play = menu("Play A Word Game? ","Yes","No");
cPLAY = CPLAY + 1;
end
if play == 0
error('TOO LATE')
end
while play == 1
fprintf("Guess the 5 letter word: _____ \n\n")
index = randi(495); %the bank of words I am using has 496 words
wordstring= string(WORDS(index));
WORD = char(WORDS(index)); % must use a character array,
fprintf('A word has been chosen. Please click to continue.')
pause()
% Setup Correct and Wrong character strings (Task 2)
wrong = 0;
right = 0;
while right < 5 && wrong < 9
clc
correct = char("_____");
badGuesses = '';
disp(correct);
fprintf("\n----- %d of 9 incorrect guesses: %s ------\n\n", wrong, string(badGuesses));
GUESS = input("What is your guess? Please enter lowercase letters only: \n", 's');
GUESS = char(GUESS);
% Check if the guess is correct or not (Task 3)
anyRight = 0
for x = 1:1:5
if WORD(x) == GUESS
correct(x) = GUESS;
anyRight = 1;
right = right + 1;
end
end
if anyRight == 0
badGuesses = [badGuesses,GUESS];
wrong = wrong + 1;
end
end

input() cannot be constrained to accept only single characters.
You could menu() or listdlg() listing the possible characters. As an enhancement, your list of possible characters could be changed to eliminate the characters that have already been chosen.
