As your morse code programs are getting smaller and smaller, they are in 
danger of disappearing!  This code trades efficiency for novelty.  I saw 
this idea at a ham club talk (in the '70's) and have been doing it this way 
ever since.  Since you guys use assembler more than anything else, I'll 
post it that way.  I do the same thing in other languages.

; Morse code, tree structured.
; Example fragment assumes the basic elements have been previously defined:

E:
     call    dit
     goto    interchar

N:
     call    dah
     goto    E

G:
     call    dah
     goto    N

P:
     call    dit
     goto    G

T:
     call    dah
     goto    interchar

A:
     call    dit
     goto    T

#pragma etc
; the 'etc' directive writes the rest of the program for you!
