[REBOL] Block/array manipulation
From: mat::b::codeplay::com at: 15-Oct-2001 16:17
Here's a simple thing which I've needed to do quite a bit of, but
couldn't quite figure out how you'd do it in Rebol so tended to do
things the long way.
Let's take a block of stuff;
Stuff: make block! ["fire" "water" "air" "water" "water" "air"]
Now the object of the excersize is to to build block with all of the
unique values. That bit is easy;
foundstuff: make block! 
foreach bitofstuff stuff [
if found? find foundstuff bitofstuff [
append foundstuff bitofstuff
After this, all of the unique values are loaded into the 'foundstuff'
The question is, say I wanted to do this but count each instance of
the words as they are subsequently found? IE I could somehow tell that
water was found 3 times and air was found twice.
This is where my rudimentary grasp of Rebol fails me. :)
