Hi Charles,

Ok, so you need:
right: func [series [series!] elements [integer!]] [
copy skip tail series negate elements
]
left: func [series [series!] elements [integer!]] [
copy/part series elements
]
mid: func [series [series!] start [integer!] length [integer!]] [
copy/part at series start length
]
>> right "abcdefg" 3
== "efg"
>> left "abcdefg" 3
== "abc"
>> mid "abcdefg" 3 3
== "cde"
Adapt REBOL to you, not the opposite.
Regards,
Gabriele.
