pointers to arrays

Oops: I forgot to add that another advantage of the "char *line[]"
approach is that you can do:

	char **cp;
	cp = &line[k];
	...
	cp++;	/* point to pointer to next line */

- there is no need for a multiplication in the last statement, and,
even more important, you can do all that in a function which does not
"know" the length of a "line" - it can be written to work with any
length, by passing the line[] to it instead of page[]!  You do have
to initialize line[] first, as posted.
