Some questions about StringSplit()

[MiserableLife]

What is the difference between

StringSplit('a,b,c,d',',',0)

and

StringSplit('a,b,c,d',',',1)

Test code:

$k = StringSplit('a,b,c,d',',',0)
For $i = 1 to $k[0]
    ConsoleWrite($k[$i])
Next

ConsoleWrite(@CRLF)

$k = StringSplit('a,b,c,d',',',1)
For $i = 1 to $k[0]
    ConsoleWrite($k[$i])
Next

ConsoleWrite(@CRLF)

This is how I see it, which means it's probably wrong..

Let's assume the delimiter string is ,.?. With flag 0, any of those 3 delimiter characters will be used to SplitTheString. With flag 1, all three of those characters are needed.

But when I run the test code, my result was:

abcd
abcd
'0'

What happened to the , in the second line? I thought the result would be:

abcd
a,b,c,d
'0'

I think with only one delimiter character, flags 0 and 1 do the same thing.

Could you explain what "needed" means ... I still don't quite understand. Thanks.

I've rewritten your code, to explain it better to myself as well

#Include <Array.au3>
$k = StringSplit('a.b,c,.d',',.',0)
_ArrayDisplay($k)

$k = StringSplit('a.b,c,.d',',.',1)
_ArrayDisplay($k)

@@" Crystal clear. Thanks.
