I'm not at all sure what you're trying to do.

I assume by "call" you mean a web request, thus:
1) index.html contains "<FRAMESET><FRAME ...> ... </FRAMESET>".
2) Each frame is a separate, completely independent servlet.

I don't understand why you're putting bodyframe and footerframe
in the same template, but if it works...

Note: using #include right can be tricky, especially if the include
file is doing anything fancy.  Often there's a way to avoid the
#include....

By "cgi-environment" do you mean servlet environment?

__file__ will work with pure Python classes, but it may do funny
things in templates.  With precompiled templates it refers to the
.py template module (not the .tmpl file).  With templates compiled
to memory, it would probably refer to the temporary file the module
was briefly written to.

This is with Webware's Page infrastructure?  It requires some work
to get Cheetah set up right with Page.  Eventually we'll have an
example of it in the Users' Guide, but not yet.  It's not clear
what good 'myfields' and 'org' are doing: they certainly aren't
placeholders but just local variables.  In short, we'd need to see
more completely how the application is structured in order to
troubleshoot it.

I assume this translates to, "On this page (which displays in one of
the frames), I want a hyperlink that when clicked, overwrites the
entire window (all frames) with something else."

This is not a Cheetah issue or a Webware issue, but an HTML issue.
Your hyperlink should be constructed like:
<A HREF="index.html" TARGET="_top">label</A>

#def myMethod($arg1, $arg2)
My arguments are $arg1 and $arg2.
#end def

$myMethod("A", "B")

t = MyPrecompiledTemplate()
print t.myMethod("A", "B")

Note: if you don't define $arg1 and $arg2 as arguments on the #def
line, they will be looked up in the searchList, which provides an
alternate way to set the values.
