Thanks, I'll check into that when I have a moment.

I'm quite familiar with K. About 1/2 year before I bumped into REBOL, I
downloaded the K evaluation version and printed out K's manuals. I've never
used K professionally, but after working through the manuals and trying out
all the examples, I felt quite comfortable with it.

K and REBOL are extremely different birds. K (a 3rd generation APL
descendant: APL - J - K) is very much streamlined for the *analysis* of
huge amounts of data and complex data structures. REBOL is more of a
general purpose scripting/programming language. K -an interpreted language
- is known for the optimized implementation of list related algorithms that
can easily outperform handcoded C programs. It does carry a hefty price
tag. When I inquired the single user license was in the several ten
thousand dollars range. At that price it is certainly out of my league. If
I'm not mistaken it is mostly used in financial analysis (banks, insurance
companies, stock brokerage houses, mutual funds, data mining ...).

I don't think REBOL is as capable when it comes to handling terabytes of
data, it's probably not as fast when it comes to manipulating lists and
doesn't have the variety of list analysis and manipulation functions. On
the other hand K doesn't come close in terms of flexibility, readability,
Internet connectivity and wealth of general purpose features.

Enjoy,

Elan
