Hi, Ed. Good to hear from you. Long time no see!
I'm sorry for the delay in getting back to you. There was a technical glitch with my password and I couldn't get on to answer you.
There is no "one-word switch" for music code in a literary context. Happily, the music and literary prefixes are now recognized in UEB, and the signs for the accidentals have been incorporated.
More good news: BANA has approved it, and the new update of Music Braille Code will soon be available.
Cheers to you.
Larry
