This is a more efficient version of the template, making use of the fact that the universe prefix doesn't change for a given book.

program:
	result = '';
	if $#chars then
# The universe name is a constant for each book. Compute it once for efficiency
		prefix = strcat(result, first_non_empty($#universe, $series, $title), '.');

# Loop through the characters adding the universe prefix to the character
# and adding a trailing comma
		for char in '#chars':
			result = strcat(result, prefix, char, ',')
		rof;

# Clean up the list, adding spaces and removing the trailing comma
		result = list_union(result, '', ',')
	fi;
	result
