From within the "main" frame, using JS, I'm trying to copy a couple variables and arrays from the
"header" frame into the "main" frame. I've incorporated a couple "alert" statements to test the
resulting data, and find that sometimes it's good and sometimes it's "undefined" . I'm thinking this
is a timing issue between the time the variables and arrays are resolved in the "header" frame, and
the time they are referenced in the "main" frame. There is no human intervention involved in either
frames, just the browsers load and execute times. How does one deal with this issue? Maybe, insert
a delay before the "main" frame is loaded or executed?
Thanks for any help.

You mean, the main frame attempts to access stuff in the header frame before
the header frame has finished loading?
When the header frame finishes loading, you could have it set a flag
variable in the main frame. When the flag is set, you know it should be OK
to access stuff in the header frame. (You'll also need to check so that you
don't attempt to set the flag before the main frame has finished loading).

Hi Joakim,
Thanks for your response. I tried what you recommended, but when I test the flag I get an
"undefined" error msg if the header frame isn't loaded and startup code executed, which of course I
don't want displayed to the client. So, I was thinking of trying to setup another almost unvisible
(only 1 pixel, borderless) frame that will maintain the interlock variable. That, combined with a
preferred frame load order, as indicated in the <frameset>, might take care of the problem. That
should get me away from the "undefined" problem. I'll give that a try later today.
Thanks for your help.
Don

Can I pass $_SESSION variables between frames? Some web pages claim it is possible, but I tried setting $_SESSION in the parent

how would I then see the java variable in the php code? Thanks very much.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
