Here's some:
>> string: "hello"
== "hello"
>> length? string
== 5
>> left: func [S [string!] N [integer!]] [copy/part S N]
>> left string 2
== "he"
>> right: func [S [string!] N [integer!]] [copy/part at S (length? S) -
N + 1 N]
>> right string 3
== "llo"
>> mid: func [S [string!] I [integer!] N [integer!]] [copy/part at S I
N]
>> mid string 2 3
== "ell"
I can't remember if there's any others. Everyone is free to use the
above as they wish.
Oh, and if you change the "[string!]" to "[series!]", they'll work on
blocks as well as strings. :-D
I hope that helps!
