You're right, it's not case-sensitive. I am sacrificing the extra few bytes of memory for the sake of speed. Passing everything through lower() takes time. Indexing everything directly is faster. If we simply "copy" the values from A-Z to a-z, it should use less memory (due to Euphoria's copy-on-write sequence management). Although if we add it all up, we're probably only saving about 400 bytes of memory.

MORSE['a']  = MORSE['A'] 
MORSE['b']  = MORSE['B'] 
MORSE['c']  = MORSE['C'] 
MORSE['d']  = MORSE['D'] 
MORSE['e']  = MORSE['E'] 
MORSE['f']  = MORSE['F'] 
MORSE['g']  = MORSE['G'] 
MORSE['h']  = MORSE['H'] 
MORSE['i']  = MORSE['I'] 
MORSE['j']  = MORSE['J'] 
MORSE['k']  = MORSE['K'] 
MORSE['l']  = MORSE['L'] 
MORSE['m']  = MORSE['M'] 
MORSE['n']  = MORSE['N'] 
MORSE['o']  = MORSE['O'] 
MORSE['p']  = MORSE['P'] 
MORSE['q']  = MORSE['Q'] 
MORSE['r']  = MORSE['R'] 
MORSE['s']  = MORSE['S'] 
MORSE['t']  = MORSE['T'] 
MORSE['u']  = MORSE['U'] 
MORSE['v']  = MORSE['V'] 
MORSE['w']  = MORSE['W'] 
MORSE['x']  = MORSE['X'] 
MORSE['y']  = MORSE['Y'] 
MORSE['z']  = MORSE['Z'] 

Wikipedia has a pretty comprehensive list of Letters, numbers, punctuation, prosigns and non-English variants for Morse code, which is what I used as a reference.
