I modified a script in Tara lab to write that matrix, I think that it need
several GB to get the job done.
a=: 65536 256 $ 0.5
theoretically it need 134MB, but actually it needs nearly double
7!:5 <'a'
2.6843546e8
to reshape this into a character array needs 800MB
7!:2 'b=: _8]\ 2&(3!:5) ,a'
805308928
and other intermediate steps that it get memory full. All this happen in this
expression.
, (toHeader 16b0203, 14) ,("1) (_2]\ toWORD0 ({:s)#r+i.{.s) ,("1) (_2]\ toWORD0,
({.s)#,:c+i.{:s) ,("1) (toWORD0 xf) ,("1) (_8]\ toDouble0, yn)

I kept running out of memory trying to use Tara to write my 65536 by 256
matrix of floating point numbers to a spreadsheet. I also had problems
*/65536 256 8

This is about 134MB only. Tara should handle it. Can you post your test
script?
I heard that Office 2007 only available in 32-bit. It that true? Could
you confirm this by looking at the task manager?
