Of course the other solution is to simply create a 2nd and 3rd User Space as
needed and dump the remaining data there.

Hi John,

When you say you're accessing the 32K chunks by address, do you mean chunk#
or something?  If you split each chunk into two physical file records,
calculation of the rrn of the chunks would be pretty simple -- rrn1 = chunk#
* 2 - 1, rrn2 = chunk# * 2.  I guess what I'm saying is that calculating the
record you want is not too big a deal.  If speed is an issue, and you think
a multiply would take too long, then try rrn1 = chunk# + chunk# - 1.

hth,
