Re: Sorting arrays

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

The main problem with all those LFs is - all those LFs - lots of index 
maintenance going on - have to create yet aNOther LF to accomodate a new 
situation.

The use of data structure arrays is quite new - in terms of the last 28 
years, anyhow. So it was necessary to use a different technique in days 
past. Now that is the simplest thing - read records into the array. 
There are issues of how many elements to have in the array, but those 
are manageable.
