I have an array with 500+ elements. Assume elements 100, 200, 300, and 400
are equal to 'Sue'. For each occurrence of Sue, I want to find the row
number for the next occurrence and for the previous occurrence. At 100, I
get 200 and 'none'. At 200, I get 300 and 100. But when I get to 300, I get
400 and 100, altho I want 400 and 200. When I am at 300, is there some way
to have the search start at 299 and search backwards so that the first match
it comes to is at 200?
