Thanks for the quick response. I agree, net.data does not do complicated
well. I apologize for not being specific. Most of the logic will be done
via calls to RPG programs (since most of these already exist). I think that
what is hanging me up is the ability to keep a single "transaction" while
going from screen to screen. In "green screen days" this would be simple -
an order number in an order header file, that is associated with all of the
items (in an order detail file). My problem is going to be keeping track of
this order number as we go from screen to screen (sometimes via HREF,
sometimes via SUMBIT). I'd rather not be passing this number as part of the
URL. I know net.data has the ability to do a persistent function, but the
documentation that I've seen for this is a nightmare. Is this the direction
- other than something like PHP which I do not yet know well enough to deal
with - that makes sense? If so, do you know where I might find some
examples of persistent macros?

Larry,
This can be done. In fact, IBM used to sell a product called Net.Commerce
(this is now called WebSphere Commerce Suite and is written in Java) that
did this very thing. The way they did it was to handle all of the
programming logic in native code and use Net.Data just for the display. IBM
gave us a demo of this (that was around 1998) and the code was very, very
ugly.
Depending upon what you're doing, shopping carts can be pretty complicated
and it's been my experience that Net.Data doesn't do complicated very well.
We (as in mostly me) ended up writing CGI programs to do all of this that
wrapped our order entry logic (the validation part is where it gets tricky,
the act of taking a product id and putting it in a table is easy). If I were
doing this today and didn't want to use Java, I probably would use one of
the tool kits (like CGIDEV2).
Another option would be to use PHP. There are plenty of examples in PHP to
get you started. Most of the ones I've seen lacked the sophistication you'd
expect of a production app but they would be a place to start.

Subject: [WEB400] shopping cart in net.data
Has anyone done a shopping cart in Net.data? I've done a lot of work with
net.data, but never a cart. I'm about to start one, but if someone knows
any samples, freeware, etc out there, I'd rather not start from scratch.
Thanks
