I was really trying to use this as a teachable moment for
the "IDL Way". :-)

READ_ASCII is great if you have 10 or 100 rows of data.
It is slow, slow, slow if you have a LOT of rows. This is
because it, by necessity, has to use the line by line
data reading method.

Plus, it so damn inelegant (IMHO) I've never used it, so
I just never think about it as a solution. :-)

Cheers,

David
