How do you define a ‘group’? If a ‘group’ is a word, how do you decide what to keep?

E.g., using a for loop to subdivide the entered text string into groups of 250 characters each (is that what you want?):

n = numel(entered_text);
for k=1:250:n
    process_text = entered_text(k:min(k+249,n));
    % process the string in process_text
end
