As Tom says, depending on the other languages, REBOLs series may have
some or all of the capabilities of their arrays -- and vice versa.
Remember that a series is not just a block....Strings (and some other
data types) are also series, so REBOL has a regular set of operations
that apply to strings as well as series. So, from another perspective,
REBOL series look a lot like regular strings in other languages :).
A couple of things you can do with block series that may not be obvious
from the core documentation.....
Each element in a block can be any datatype:
blk: copy [99 "a" 1-jan-2010 [1 2 3]]
== "a" ;; is a strings
== 99 ;; is an integer
== [1 2 3] ;; is another block
insert at blk 2 1.1 ;; insert at new entry at position 2
== [99 1.1 "a" 1-Jan-2010 [1 2 3]] ;; inserting has shuffled down the
entries to make room -- more like a list in some languages
append/only blk blk
== [99 1.1 "a" 1-Jan-2010 [1 2 3] [...]] ;; blk now contains itself
Have fun playing with series!
