Just as a warning - do not forget the duplicate below. If you leave it off, structAppend makes pointers like structCopy does (ie, not at the top level, but in nested structures). Example:
<cfset a = structNew()> <cfset a.mod = "moo"> <cfset a.lower = structNew()> <cfset a.lower.mod = "moo2"> <cfdump var="#a#"> <cfset b = structNew()> <cfset structAppend(b,a)> <cfset b.mod = "one"> <cfset b.lower.mod = "two"> <cfdump var="#a#"> Notice how a.lower.mod is modified by the change in b. ======================================================================= Raymond Camden, ColdFusion Jedi Master for Hire Email : [EMAIL PROTECTED] WWW : www.camdenfamily.com/morpheus Yahoo IM : morpheus "My ally is the Force, and a powerful ally it is." - Yoda > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:Douglas.Knudsen@;alltel.com] > Sent: Tuesday, November 12, 2002 10:55 AM > To: CF-Talk > Subject: RE: Locked Out > > > Sandy, > > Cool tag.
