Hi Gregg,
I'm not quite sure what you are up to here. I gotta say too, I had never
seen ALTER before, cool!
Look at this comparison:
a: "the"
b: "quick"
c: "fox"
block-of-strings: reduce [a b c]
clear b
Now if clear the b string:
>>probe block-of-strings
== ["the" "" "fox"]
So b refers to a string and so does the block, when you clear the string you
see it get cleared for b and in the block.
Picked in the text/list is exactly the same. It refers to one of the strings
in your block of strings. Using alter I suspect
is modifying the block in such a way that you are breaking the references
that have been set up by VID.
I have to rush off. Maybe others can be more clear.
Brett.
