[REBOL] [Find] Frustration with Find
From: pwawood:mango:my at: 1-Nov-2004 9:10
I'm finding the behaviour of 'find to be a little counter intuitive.
When the value being searched for isn't found find returns none! rather
than the tail of the index.
I wanted to code like :
str: "abcde"
if not tail? str: find str "1" [......]
However this throws up a script error as the value of str is set to
none! and it is now "disconnected" from the series!
>> str: "abcde"
== "abcde"
if not tail? str: find str "1" [......]
** Script Error: tail? expected series argument of type: series port
bitset
** Near: if not tail? str: find
>> type? str
== none!
I'd appreciate any comments and insight on why find returns a none!
value in these circumstances?
