Sorry -- "symmetrical"? Please elucidate, I'm not familiar with
this term in this context. Which factors need to be the same on
both sides of the Turing box lid for your criteria to be satisfied?

Arrrgggg... my head hurts :-)
Okay, a little misunderstanding here.
In my statement of symmetrical requirements regarding communication I
basically said:
1. js -> php
2. php -> js
I was simply using symmetrical *statements* to illustrate my point. I
was not implying a requirement that all communications must be
symmetrical, understand?
Now, I know [1] that js can pass variables to php and cause it to run
-- I do that using ajax -- that's not a problem.
What I don't get is how php can pass variables to js and cause it to
run "at will". I can see how php can, and have used php to, generate
a web page which has <body onload="js()"> tag, which can pass a
variable to js and will cause js to execute. But, isn't there
anything else? Is that all there is?
Paul you said:
All this seems very obvious to me, but knowing your level of
sophistication with programming I'm led to suspect that perhaps I'm
not understanding your question properly.
Thanks for the compliment, but I can be as dumb as a post about
things until I fully understand them. However, everything you said I
understand.
I understand that XMLHttpRequest works -- I'm a little fuzzy about
how -- but, I have used it to both send data to php and to cause php
to execute. That's not a problem.
I also understand that php can generate html (have done it) and echo
out javascript that may, or may not, run if js is present -- like
Robert suggested in his WAHOOEY (LOL) example. But, that appears
messy to me. If php wants to say something to js, then a page must be
created -- it seems like a lot foreplay to get at the goodies.
I guess what I'm looking for is something simpler -- is there?
tedd
PS: WAHOOEY indeed -- LOL, I'm still chuckling about that.
