This's my function:

Function NonDupe
Lparameters lcStr
xRet=""
xLen=Len(lcStr)
Do Whil !Empty(lcStr)
	xCh=Right(lcStr,1)
	lcStr=Left(lcStr,Len(lcStr)-1)
	If !xCh$lcStr
		xRet=xCh+xRet
	Endif
Enddo
Return xRet

I don't know whether if my code faster or slower than others. I just a few lookup to others, I suppose my code is different. I hope noone blame me about being Code Hood... :)

If Walter would be took and developed Marcia's code there would be not a problem because all of codes at there are SHARING, I can't see any problem. This would be not steailing, this would be just inspire.

I know this's not my business but; I would not call John as Troll. I suppose John is older than me and Tore. In my country we try respect olders if even they're sometimes not being polite... ;)
