You misunderstood the notation. The | means "or", it is not something
you have to type literally.
So the syntax is:
either a line number (maybe in a different file) or a function name
optionally followed by a condition after a comma
So in your case probably something like:
break Old_MacDonald:23, name[indx] == 'd'
(I'm not sure what "indx = 4" was supposed to do. You can't assign
inside of a condition.)
