In simplest terms: In Revolution, an array is a container that holds keys, and each key is a variable.
An array can be thought of as a box containing a number of smaller boxes. myArray[1] would be a box named "1" that is contained within the larger box named "myArray". The inner boxes do not have to be named numbers. You can also have myArray["mybutt"] or any other valid variable name. If you do this: Put "myButt" into myVariable Put "way too scrawny" into myArray[myVariable] Then the words "way too scrawny" will have been put in a key named "mybutt" inside an array named "myArray" Arrays reside in memory, but are not saved. (although you can have global arrays, which stick around after the handler runs, but are not saved onto disk) If you want an array to be accessed by multiple users, you would need to save it as a custom property set. Custom properties and custom property sets can really be quite confusing until you get used to them. They use the same type of notation as arrays. I would suggest reading the docs about custom property sets very thoroughly, then coming here to ask questions about those things that are still confusing. You can create a data stack that stores information in custom property sets. You can keep that data stack on a shared drive, and allow everyone to search that custom property set from their computer. I warn you in advance, there are quite a few pitfalls to be wary of if you choose this method - but if you get it right, Revolution searches custom property sets very fast. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of keith Sent: Monday, July 25, 2005 12:00 PM To: How to use Revolution Subject: array info request (was: Re: Rant Re Rev Documentation) Sometime around 25/7/05 (at 01:19 -0400) Thomas McGrath III said: >I always learn best by example. Absolutely! Speaking of learning by example (or any other method, I'm not fussy! ;-) is there anything around that could help me get my head around arrays? Some kind of simple guide that doesn't start out at too high a level? Gotta start sometime! :-) I've made a bit of headway by dissecting and rebuilding a few simple things from past threads in this list, so I can put the contents of a set of fields into a line in an array in a card's user property and then pull specific elements (items?) back out again. What I'm wondering is whether arrays would be a useful way to store data which is to be accessed by more than one person across a network? There're perhaps 30 different fields and popup menus, and some of the fields will contain a few paragraphs of text each. (Yes, paragraphs. So returns have to be accepted in the data, in case that makes any difference.) I had been experimenting with using a text file on a networked computer (as suggested here), with the first item on each line flagging whether it could be edited or not. Editing a record involves reading the record, parsing the data into fields, making the changes there, then writing it all back out to the same record again. I'm hoping to add search abilities, and I wondered if using a data array might be more efficient... but I'm definitely fairly in the dark about these structures! I presume an array is a kind of data structure that has to be stored in a stack in some way, perhaps as a user property? It seems to be layered in a more complex dimensional way than can be represented in a flat text file. Or am I assuming more complications than there actually are? k ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
