Hi Jim:
I found a message from Dennis Brown who explains the usage and reasons
for the use of scoping function calls. You will be able to find
examples of this in the Microsoft word2007 scripts. Here is the message
I found.

Hi,
Those are new "scope" identifiers, needed because Outlook 2007 uses
Word as
the editor exclusively. Using SwitchToConfiguration to launch the Word
script set became very problematic, especially when dealing with
exchange
server timing issues.
These identifiers tells Jaws which specific function to call.
For example, the FocusChangedEventEx is the first event triggered on a
focus
change.
Microsoft Outlook 2007 has one, as does Microsoft Word 2007,
MSOffice2007,
and default.jss.
They drop through if not redirected.
When going into a message, and the Word functions need calling, not the
Outlook functions, then the FocusChangedEventEx needs to be redirected
to
the correct function, otherwise it would call the Outlook
FocusChangedEvent,
which would call the Outlook SayFocusedObject, and Outlook
SayObjectTypeAndText, none of which are used in the message body in
Outlook.
So, in Outlook's FocusChangedEventEx, we caused it to look for the
class of
the message body, _WwG, and if the current class, then redirect it to
call
the Word's FocusChangedEventEx function, so the Word functions could
process
the message body.
Microsoft_Word_2007::FocusChangedEventEx(...)
Now the correct functions get called, and no constant switching of
script
sets, vulnerable to timing issues.
Self::
is only when you want the current script set's instance of that
function to
be used.
Scope is redundant if the functions would be called by simply dropping
through. For example,
; Overwritten event in MyScripts.jss...
Function ValueChangedEvent(...)
If GetCurrentControlId()==4444 Then
Default::ValueChangedEvent(...) ; Calls default.jss
Return
EndIf
ValueChangedEvent(...) ; Drops through to default.jss anyway.
EndFunction
If default is the next set, and you are already letting it drop through
to
default, then no scope is needed.
Also, be careful not to get into a loop. You should never call up the
chain, only down, otherwise you continually call the current function.
In this example, the Word scripts don't use anything in the Outlook
script
set, so a scope to an Outlook function should never be used in the Word
scripts, since the Word script set is called in a "use Microsoft Word
2007.jsb" line within Microsoft Outlook 2007.jss file.
Hth.
Thanks,
Dennis Brown
