Converting language into morse code

Hi! My professor recently assigned a project on converting words into morse code. I won't have this site do my homework for me, but I had some basic questions on how to approach it. Part of the project is to have lower case letters give the same output as upper case letters, and I don't really understand how to do that. I tried just typing in A=a=MC_'.-.' or A=a & A='.-.' or a bunch of if____ statements, but it kept giving me errors, like A is an undefined variable. How can I fix that? Is there a specific command?

‘Way back when, there was a File Exchange program called morspeak, but I couldn’t find it again when I just now looked. (I modified it to add numbers, renaming it morspeaknx.) I've uploaded it here. I used it back when MATLAB and all personal computers were s-l-o-w, and I needed periodic progress reports on how the simulation was going, while I was doing other things. (I’ve been an Amateur Extra Class ham radio operator since 1968, so it was meaningful to me.) Use it or not as you wish.
