RE: %lookup

Does binary search still apply if I pass the start index to %lookup?  And 
doesn't array by default ascending?


Here is what I'm dealing with.  I need to load some data in a file to an array 
and then do a lookup in this array.  Because  many records are in these file, 
I, therefore, try to use a number that is big enough to support grow.  Of 
course, the bigger the array, the longer the search.  I'm thinking if I can 
sort it first and then tell lookup to search from the first non blank index, 
that will reduce the processing time.

First, if the array is 
unsequenced, a sequential search is used. But, if the array is defined 
with either ASCEND or DESCEND, then a binary search is used.
