Hi Daniel,
I notice Brett has just posted similar stuff to the following, but
this is what I came up with anyway...
This function should do what you want...
to-chars: func [str /local word][
word: copy []
forall str [append word str/1]
word
]
>> to-chars "hello"
== [#"h" #"e" #"l" #"l" #"o"]
>> to-chars "goodbye"
== [#"g" #"o" #"o" #"d" #"b" #"y" #"e"]
However, depending on what you're doing, you may be able to get the
results you want without needing to convert a string to a block, as a
string is already a series of characters. So, the following gives
the same results...
>> str: "hello"
== "hello"
>> str/2
== #"e"
>> word: to-chars str
== [#"h" #"e" #"l" #"l" #"o"]
>> word/2
== #"e"
HTH.
