Mike, I've got the wrong head on to day (my SQL one, the CF one is getting dusty at home) but IIRC, struct keys can't have numbers as names (at least at the start) segment[page_#counter#]thispage = counter; should work tho...

[cfaussie] Re: Struct notation - whats wrong with this?
Mike, It is not very clear, how you have defined this. If segment is a struct, then you can't do segment[#counter#]. If it is and, segement.1 is an element of segement, then you can't use numbers as the beginning of the element name. I would have assumed that this would have been an array with structures.

Yes! thanks Paul, that did work indeed. Barry you shouldn't be at work without your CF head on.

[cfaussie] Re: Struct notation - whats wrong with this?
So is segment an array of structs? Ie cfset segment = arrayNew(1) / cfset segument[1] = structNew() / cfset segment[1].thispage = 1 / From what you have, it looks like the numbers are structs, which doesn't make sense, the array method makes more sense.

Good This will also work: segment[#counter#]['thispage'] = counter; segment[#counter#]['nextpage'] = (counter + 1); segment[#counter#]['content'] = #contentelement#; Extending it further you can mix arrays into it as well: segment.3.myarray = ArrayNew(1); segment.3.myarray[1] = 'a'; segment.3.myarray[2] = 'b'; segment.3.myarray[3] = StructNew(); segment.3.myarray[3].a = 'a1'; It's probably safer to use the square bracket notation, because having a numeric struct key as a child of a parent that is an array causes an error. (what?) segment.3.myarray[3].2 = 'a1'; causes an error segment.3.myarray[3][2] = 'a1'; is fine segment.3.myarray[3]['2'] = 'a1'; works as well.

[cfaussie] Re: Struct notation - whats wrong with this?
Mike, to your point about using square bracket notation not being in the docs, are you looking only at the Reference manual? Not everything is documented there, or it can be hard to find, with its primary focus on tags and functions. But I'd be surprised if it wasn't at least covered in the Developer's Guide (the 1100+ page guide that is often missed). It's nearly 11pm here in the US, so I'll leave it to others to find where it is documented, if interested.

[cfaussie] Re: Struct notation - whats wrong with this?
Charlie I'm sure it is documented somewhere. Those docs are very comprehensive. But right now, with a deadline against me and the search on CFDocs not bringing something up about it, I used the rather rash statement that it's not covered. I probably shouldnt have said that. As to the reason for using the numeral as the name of one of the structure elements - i used that because it's a page number. Normally i'd use a meaningful word as a variable name, but in this case it's a page number, which in the context of this task is indeed meaningful. It's part of a pagination functionality.

Did you find arrays too Andrew, I thought they must have been hidden for
someone to write structs such as this.
I might start doing arrays like this
cfset myArray = structNew() /
cfset myArray['1'] = 'row 1' /
cfset myArray['2'] = 'row 2' /
