Thanks for the suggestion, Sean, but exporting nto access isn't an option
(right now). I'm going to begin saving the data more freqently. Here's my
thinking: The data or the spreadsheet, actually, is saved on a network drive,
so I'm thinking that if I have data on the drive, open the spreadsheet and
add more, but not save it, the data must reside on the PC, not on the
multi-gig network drive.

I'll let you know what happens.

I would suggest exporting into Access instead. You can always run an External
Query in Excel at that point to pull what you need...

I'm working with large arrays of numbers: 1001 x 1001. I compute the arrray

spreadsheet, putting each array under the previous.

When I get to about row 29,000 (sometimes) or row 40,000 (typically) excel
sends me a note saying that (and I'm paraphrasing it) "...Excel cannot
[handle]the data with the resources it has. Choose less data or close some
appications."

I have 3G of RAM on a Dell Optiplex 755 with an Intel Pentium Dual CPU E2160
@ 1.80 GHz.

Any advice?
