Richard, that is an excellent document, and identifies what looks like
a much more "Revolution way" of doing things. In fact, in my current
app, I do pretty much everything you've described there, so I guess
I've done some things right and Rev-like after all. Now, about session
data and relational session data... THAT I've never tried to do with a
Perhaps some kind of example will help after all. Let's say, I have an
application which on launch, collects data from various sources, the
user's system, some stack and card data, an XML feed, some remote
images, some local images. This data has logical groupings and
interrelationships which need to be created and maintained. As well as
performing searches on this data the user also needs to find similar
and related (near) groups or items.
Using the data stack method, is it sensible to create a stack, sort the
data into it, use Transcripts powerful stack and card manipulations to
perform session functions... and then simply never save the stack? Is
this how the system is designed to work in the first place? A temporary
stack as an advanced multi-dimensional variable? If this is the case, I
think I like that much better than trying to force my own metaphor down
the throat of Rev by trying to create multidimensional arrays inside
something which really has no support for them. It sounds as though the
speed should be there, as well as the multi-datatype storage....
Believe it or not, folks, these are big mental shifts if you don't come
from a stack and card nature of programming. But, I'm trying... I want
to understand and use "best practice" techniques.
