Hi Chris,

That was probably me. Your message prompted me to take a look at that 
code for the first time in a long time and it is indeed a *small* 
fraction of Numeric functionality.  That being said your welcome to try 
and do something useful with it. I'll go ahead and send you the file in 
private email to avoid cluttering the list.

If anyone else wants a copy let me know.
