RE: 3d table or list to file

Hi Shawn,

It is possible -- just write them.  For example, the following sequence
leaves tst and newt equal.
	tst = Table[{i, j, k}, {i, 5}, {j, 5, 10}, {k, 25, 30}];
	Dimensions[tst]
	tst >> "multi.txt"

	newt = Read["multi.txt"];
	Close["multi.txt"] 

The catch with this, is that your file is in 80-column wrapped input form
and so might not be particularly useful with other programs (eg. Excel).
Mostly, I find it more useful to write the file in simple columnar format
via a Do[]; loop.

Regards,

Dave.
