Hi Erin

Don't forget that 32-bit versions of Windows (I guess you're running
on Windows since you are importing data from Excel ?) limits the user
process address space to 2GB.  My advice would be:

a) Figure out the memory usage of your program, actual and planned.

b) Determine whether or not more RAM will actually solve the problem.

c) If it will, get the extra RAM.  If it won't don't !

(I'll only whisper the next bit, it's heretical -- but it's almost
always cheaper and less error-prone to buy more RAM than to rewrite a
working program; trouble is it's not always a successful strategy.)

Regards

Mark
