Re: Data Arrays

["James W. Kilgore" <qappdsn@xxxxxxxxxxxxx>]

Peter,

I must be having a case of Fridayitis, but don't get it.  AFAIK, unless the 
names
are different you are only looking at a single instance at any particular point
in time.

Now arrays that have an index do allow you to compare two entries at a time, but
still the same instance.

You could replicate an array by overlaying a data structure but you would not
have two instances nor elements from each array instance available at the same
time.

Or am I just locked into classic RPG thinking?  I just had a thought, is there a
method through pointers to mimic multiple dimensional arrays?  Do you wind up
changing all of your calculations to use pointers and base pointer off sets
instead of field names?  How ugly, although possible, would this get?

Gads, I just had an assembler shiver run up my spine!  It's going to take me all
weekend to get over it. ;-)
