Ok, I am missing something extreamely simple here.

All I want to do is take a list of names, and using StringSplit copy them into another list separated with a carriage return. This is what I came up with, but copying to the new variable in the loop isn't working:

Code:
Players = Frank Bob Hank Bill Dale Tom

StringSplit, Order, Players, %A_Space%

loop, %Order0%
{
  Names += Order%A_Index% 'n
}


Arrgghh... It's always the simple things!! Maybe I'm just tired

Thanks in advance

use code-tags next time please

u missed the wrong operator should have been .= instead of +=
+= might be used when using numbers (integer, float point) and adding these. .= is used when putting strings (e.g. simple text, binary data) together

use it like this

Code:

StringSplit, Order, Players, %A_Space%

loop, %Order0%
{
  Names .= Order%A_Index% 'n
}

Thanks,

It works untill I try to add the 'n! Then I get an Illegal character error.

Code:

Players = Frank Bob Hank Bill Dale Tom

StringSplit, Order, Players, %A_Space%

loop, %Order0%
{
  Names .= Order%A_Index% `n
}

SplashTextOn, 300,300,,%Names%
Sleep, 2000
SplashTextOff

Maybe I'll expand on what I'm trying to do.

If I have a list of names (between 2 and 10)

Say:
Names = Joe Bob Hank Brian Elliot

I always want "Hank" to be the last name in the list, with everybody in the same order. In the above I just want the names shifted 2 to the right to be :
Names = Brian Elliot Joe Bob Hank.

Should be simple enough but I have been struggling for over an hour now!

Thanks

Why not
Code:
StringReplace, Names, Players, %A_Space%, `n, All
Question

The Mad Scientist at work!

Then:
Code:
Players = [VxE] Frank Bob Hank Bill Dale Tom
Stringreplace, Players, Players, %a_space%Hank%a_space%, %a_space%, UseErrorLevel
If ErrorLevel
   Players = %Players% Hank
StringReplace, Names, Players, %A_Space%, `n, All
MsgBox, %Names%

always puts Hank at the end Crying or Very sad

This puts Hank at the end, but it doesn't keep the names in the same order. In your example, I would want the list to read:
Bill Dale Tom [VXE] Frank Bob Hank

I have tried about 6 different ways and am missing something simple.

Thanks for the reply... All answers help with my understanding!

Sorry, missed this post. Here are two different methods:
Code:
Names = Joe Bob Hank Brian Elliot
Names := RegExReplace(Names, "(.*) Hank (.*)", "$2 $1 Hank")
StringReplace, Names, Names, %A_Space%, `n, All
MsgBox %Names%
Code:
Names = Joe Bob Hank Brian Elliot
Names := SubStr(Names, (i:=InStr(Names, "Hank"))+5) " " SubStr(Names, 1, i-1) "Hank"
StringReplace, Names, Names, %A_Space%, `n, All
MsgBox %Names%

Regular expressions are generally considered an advanced topic, but I think in this case the regular expression is easier to follow.

as a good entry for regex the help about regexreplace, regexmatch and regex overview are quite simple to read, also dont miss PhiLho's tutorial which explains some more advanced themes on http://phi.lho.free.fr/programming/RETutorial.en.html
