Well, the routines are getting called fine now, but the program isn't
fading, it just waits a bit then displays the finished text.  Is my
method of changing the contrast correct?
Here's the routine to fade to white:

FadeToWhite:
   ld    a, (CONTRAST)
   push  af
   ld    bc, 48            ; Wait 1/4 of a second before fading any more
FTWLoop:
   dec   a
   ld    (CONTRAST), a
   #fncall  DELAY
   cp    0
   jr    nz, FTWLoop
   pop   af
   call  CLEARLCD
   ld    (CONTRAST), a
   ret
