Hi Robert
It is basically the same. IIRC when I first wrote it, the DEMO function was
not available or not documented. These test-panel (which was originally
called demo) start-up functions changed thru several different builds of
View.

with IE and click on the English link, the page URL
is:

which is the one desired. Seems to be a problem with resolving to the
correct URL.

Hi Mat
The question is, if I get a string which contains a mathematical
expression - how would you evaluate this and get the result?
Here is one way:
str: "3 + 4"
== "3 + 4"
either not error? try[result: do str][result]["code to handle error"]
== 7

Hope this helps

Subject: [REBOL] 32 bit - dword values
How do we h
Hi David
This is one of the most irritating shortcomings of REBOL. It provides NO
method of formatting floating point numbers, other than it's default. There
are some scripts at http://www.rebol.org which will do this. The most
comprehensive and accurate is format.r by Eric Long.
