RE: Array issue

From: Barbara Morris

Or for the LOOKUP opcode, you can set the factor 2 index to 901 before
the LOOKUP:

C                   eval      n = 901
C     'x'           lookup    myarr(n)                               10


The technique Barbara notes has been available for as long as I can
remember; in fact, that's how we old dinosaurs used to save cycles when
trying to weed out duplicates.  We would load our array BACKWARDS, starting
with the last element, and then do a lookup with a starting position.

The other option was to make the array ascending and prefill the array with
*HIVAL (or descending and use *LOVAL), but a lot of times we didn't have the
luxury of getting our data to us in a sorted fashion.
