Well,

I like the idea, but unfortunately, these things pop up...

Also, it's not that easy. As opposed to what I wrote below,
there are some (a few) features that ONLY work if you specify
"JavaScript1.2" in
Netscape 4...   :-(


But good luck!

Oh dear...

Well what I was intending to do was to write a macro for my favourite
editor (freeware/shareware: www.notetab.com) - one where you can
add clips.

This macro (so far) looks like this - if you download notetab and try 
to
add a clip you may want to see my idea in practice:
-------------------------
^!Set %browser%=3D^?[Browser version=3D_None specified|Navigator 
2.0|Navigator
3.0|Navigator 4.0-4.05|Navigator 4.06-4.7x|Navigator 6.0 |Mozilla (open
source browser)]
^!If ^%browser% =3D "Navigator 2.0" ^!Set %js%=3D"JavaScript 1.0"
^!If ^%browser% =3D "Navigator 3.0" ^!Set %js%=3D"JavaScript 1.1"
^!If ^%browser% =3D "Navigator 4.0-4.05" ^!Set %js%=3D"JavaScript 1.2"
^!If ^%browser% =3D "Navigator 4.06-4.7x" ^!Set %js%=3D"JavaScript 1.3"
^!If ^%browser% =3D "Navigator 6.0" ^!Set %js%=3D"JavaScript 1.5"
^!If ^%browser% =3D "Mozilla (open source browser)" ^!Set 
%js%=3D"JavaScript
1.5"
^!If ^%browser% =3D "None specified" ^!Set %js%=3D"JavaScript"

<script language=3D"^%js%">
<!--
// Optimized for ^%browser% (and above.)
^&
// -->
</script>
-------------------------

I could just change the if-sentence to give just 
'language=3D"javascript"' if
people choose netscape 4... (though some of my idea is not so smart 
then :
-)

Good initiative,

but there's a small problem regarding this:

In Netscape 4, if you specify version, the JavaScript interpreter
misinterprets some
stuff that will work otherwise.


"...specifying a LANGUAGE attribute of "JavaScript1.2" makes navigator 
4
behave in ways that
are not compatible with previous browsers and not compatible with the 
ECMA
specification.
For this reason, you may want to avoid specifying "JavaScript1.2" as a
value
for the
LANGUAGE attribute".

edition)

Hi,

When you write javascript code it is a good practice to specify which
javascript you are building your code on. It is done this way:

     <script language=3D"JavaScript1.1"></script>

Obiously for version 1.1 :-)

Can anyone help complete this list of compabillities between 
JS/Browser's:

JavaScript 1.0
  Netscape : Navigator 2.0
  Microsoft: ?

JavaScript 1.1
  Netscape : Navigator 3.0
  Microsoft: ?

JavaScript 1.2
  Netscape : Navigator 4.0-4.05
  Microsoft: ?

JavaScript 1.3
  Netscape : Navigator 4.06-4.7x
  Microsoft: ?

JavaScript 1.4
  Netscape : -
  Microsoft: ?

JavaScript 1.5
  Netscape : Navigator 6.0
  Netscape : Mozilla (open source browser)
  Microsoft: ?

All my information about Netscape/Mozilla comes from:
http://developer.netscape.com/docs/manuals/js/core/jsref15/preface.html#
1003

Thanx,
