renaming arrays

hi all, how do i rename:
gTestVariable["OldName"]["MoreSubKey"]["Key"]
to another key on the same variable?
gTestVariable["NewName"]["MoreSubKey"]["Key"]
Thank you for the answers....
P.S.
I have noticed that using
keys(arrayVariable) returns the keys in alphabetical order... How do I prevent this from happening?

shadowslash,
Here's an example that shows how to "rename" a key:
Code: Select all
on mouseUp
put "x" into gVar["x"]["1"]
put gVar["x"] into gVar["y"]
delete variable gVar["x"]
put the keys of gVar
end mouseUp
Arrays are useful, because they have no particular order at all. Why do you have a problem with the way the engine reports the list of keys?
Best,
Mark

It's because I'm going to use it to store data,
e.g.
Data Blue
Data Green
Data Yellow
Data Red
Data White
Data Black
Let's say those are
Chapters in a book. Of course chapters in books shouldn't rely on being alphabetically sorted. Now I'll use
keys(data) to retrieve the keys. As like a book, I want it to remain the way I added them to the array so that I can easily reference using the
keys() function. If not, an alternative would also be great.
EDIT:
Chapters in books might not be the best example because I know chapters can be called like
Chapter 1: Data blue, etc. So I'll just re-assure my statement, whatever the example is, I really wish it would remain the same order as how each key was filled in.

shadowslash,
The chapters in a book can be stored in an array, but you need to add additional information. For example, you could add the number of the chapter as an additional key. For example:
Code: Select all
gVarArray // name of var
[name of chapter 1] // primary key
// secondary keys:
[key type] //="chapter"
[chapter number]
[chapter data]
[chapter length]
[author]
[number of pages]
[additional remarks]
[name of chapter 2] // primary key
etc.
Or you could use a different approach, which uses the chapter numbers as keys:
Code: Select all
gVarArray // name of var
[number of chapter] // primary key
// secondary keys
[chapter data]
[chapter length]
[author]
[number of pages]
[additional remarks]
[number of chapter] // primary key
etc
Whatever suits you...
Best,
Mark

Interesting stuff, I managed to do the constant arrangement via:
Code: Select all
gArray
[Chapters]
Blue <-- THIS IS THE VALUE OF THE [CHAPTERS] KEY
Yellow AS YOU CAN SEE, IT'S A RETURN DELIMITED PLAIN TEXT LIST
Brown
Black
Green
Red
[Blue]
[Summary]
This is the summary of this chapter.
[Characters]
These are the characters that appeared on this chapter.
[Yellow]
[Summary]
This is the summary of this chapter.
[Characters]
These are the characters that appeared on this chapter.
[Brown]
[Summary]
This is the summary of this chapter.
[Characters]
These are the characters that appeared on this chapter.
etc, and so on...
So I basically keep track of the arrangement of the chapters in just another key called "Chapters".
That way, even if I re-arrange the chapters there, the rev app would still read it from the correct array key.
