Alex,
Went to your page, and wow, that is exactly what I was trying to
do. I'm still trying to figure out exactly how you do it, but I'm
headed in the right direction.
Thanks!

Hi Tim,
I think there are many easy ways to do this - and many
not-so-easy ones too.
IMO, easiest for something simple like this is to just use the url.
See tweedly.net/page_by_url.txt for the code, or try it out at
tweedly.net/page_by_url.lc
(or try tweedly.net/page_by_url.lc?row=14 )
You can do something very similar using a cookie, with the 'row'
value stored in the cookie each time (remember to "put cookie
..." before *any* other output.)
Or by using the cookie to hold the name of a file in which you
store this kind of info. This is necessary if you need to store a
lot of data - if there is not already a cookie, create a filename
using something like uuid(), and store the file name in it - then
retrieve the cookie, and read or write the file.

Hi Matthias,
It is user specific, but I just tried the saving to a text file
on the server -- very fast. Got the user IP from $_Server, and
used that in the filename for easy later retrieval. How much
data can a cookie hold? Guess I'll test that.
One of the reasons I'm fussing with this is I'm trying to come
up with some kind of pagination system. I'm probably trying to
re-invent the wheel -- badly.
It's a simple membership list, with a few hundred records. Only
want to show 30 on the page at a time. I wonder if anyone has a
LC sample for doing that. I tried Ralph Bitter's Revigniter but
just can't wrap my head around it.
Using MySQL for testing, so could try to figure out using the
CURSOR feature. But know nothing about avoiding injection
attacks, so may fall back to using a .csv for the datafile.
I've done that for all my other projects....
Anyway, thanks for the info; no global variables, but file
saves look like they'll work!

Hi Tim,
does the variable have a user specific value or a value, that
changes from time to time, but is the same for all users?
I've done something some time ago and used a text file on the
server which stored that value. In my case the value was not
user specific so it was an easy task.
If the variable is user specific, why don't you use a cookies
for that? That will grant that the value is available at all
pages in the same domain.

Matthias

As always, appreciate everyone's help.
Have made several little projects using LC Server on the
on-rev.com host. For the first time, I would like a global
variable -- that is a variable that would retain it's value
even if the page is re-loaded. Or if a user goes to another
.lc page/file in the domain.
All my playing around, and Googling around, has been for
nought. Is there a way to hang on to a bit of data was you
move around pages in the same domain?
Thanks.
