Just type your string UP means uppercase LW means lowercase Feel free to use with credit and link please :)
I figured out that the only part of scratch that has case detection was the [set costume to ___] block! Theres probably some other ways too though... But what I did was basically just create each costume so: a,A,b,B,... I then go through each letter and match it to a costume, if the costume # is even (indicating its uppercase because I have it set up as a,A,b,B), then say even, otherwise say odd!
