I have a page with two frames. Frame1 contains an inline script. Frame2
contains inline and 2 loaded scripts. How may I call a function in
frame1(inline) from frame2(inline or loaded)?

You have one page, which is a frameset. It contains two other pages
in frames.
To access a global variable of frame1 from frame2, you just write (in
frame2):
parent.frames['frame1'].globalVarName

Incidentally, I liked the page, though you could have mentioned browsers
that lack the window.open function (PDA and embedded) in the "Problems
with opening windows" section.

One of the interesting things in opera 6.0 on Series 60 Symbian
devices is that javascript defaults to OFF, but pop-ups default to on,
which seems kind of odd.
(I hope to be looking further into Opera/Netfront and others on Series
60 phones so, both claim DOM/DHTML)

I recommend against having the same "name" and "id" attribute values.
In both HTML and XHTML, "name" is a valid attribute name for frames.
If you need the "id" attribute, add "Id" to the end of it, or something
similar.
=========== debugger.html =============== =============== ======
var DebugPrint = function(_line) {
debugFrame.docu ment.writeln("< p>"+_line+"</p>");
If we are in the debugFrame, then it suffices to write
document.writel n(...);
The scope rules will garantee that we always refer to the current
frame's document object
You should escape the "</" token. The recommended way is "<\/".
I.e.:
document.writel n("<p>"+_line+" <\/p>");
}
function Initialize() {
debugFrame = window.parent.f rames.debugFram e;
This is in the debugFrame, so "debugFrame = window" should be
equivalent.
DebugPrint("Deb ugger started.");
Here you make a document.write to the current document. That completely
erases the current document and starts writing a new one. Erasing the
current document also loses the debugFrame function. So, if this page
loads faster than the program page, then it erases the function before
it can be called.
=========== program.html =============== =============== ==========
var Print = function(_line) {
programFrame.do cument.writeln( '<br>'+_line+' </br>');
As above. Change "</br>" to "<\/br>". The "programFra me." isn't
necessary ...
}
function Initialize() {
programFrame = window.parent.f rames.programFr ame;
.... and this can be shorter (or omitted)
Print("Program started.");
Here you erase the current page. The running function isn't lost before
it finishes, so the next line is executed.
window.parent.f rames.debugFram e.DebugPrint("F rom Program"); // error
this line
If this frame loads faster than the debug frame, then the function
isn't available yet. If it is slower, the debug frame erases it again.
There is a very narrow margin where this could possibly work.
message: Statement on line 9: Expression did not evaluate to a function
object: window.parent.f rames.debugFram e.DebugPrint
.... and therefore it most likely fails every time.

I have a question: If I have a frameset, frame1 and frame2.
On frame2 I have a datagrid, on which I can add/update/delete rows.
