I have a major improvement ideaby Lisztfr (no login)
But this needs a lot of thinking. The goal is to use less PUT statements, therefor i should PUT/GET the letters 2-4 at times in the lower right corner and so prepare the next screen. Kind of screen buffering for the poor man.
1) Set up another array for holding the clusters of letters
2) since font is not fixed i should know in advance how many integers i need for each size of the screen part gettet, for example 3 "!!!" will need less space than 3 "WWW"....
3) Be able to print that stuff.
