I can't think of an example of the Self scope identifier off the top of my head, but in most cases, if the function is in the current script set, no identifier is necessary. As for your second question about using scope to call a function that resides in a script set that isn't referenced in a use statement, or in default, there is no way to do that because the script set in question would not be loaded at the time. You'd need to tell Jaws that you wanted to use that script set's function within the current application, which is what the use statement is for! <grin>
As for an example on calling a script up the chain...You can do that as long as you are not calling it from the same function that would get called in the current level script set. For example,
In Outlook 2007, if you had use "Microsoft Word 2007.jsb" and you had Function SayLine() If NoMoreMessageItems() Then ; Message list is empty... ReadStatusLine() Return EndIf SayLine() ; Drops to the SayLine in Word 2007. EndFunction And in Word, you had Function SayLine() If gsApplicationName=="Outlook" Then ; In Outlook, but in the message body. Microsoft_Outlook_2007::SayLine() ; Calls the Outlook SayLine function. Return EndIf SayLine() ; Drops to the SayLine in default. EndFunctionThis would cause the loop effect, since the Outlook SayLine would drop into the Word SayLine, then the Word SayLine would call the Outlook SayLine.
If you had the Word SayLine function call something other than the SayLine, then it would be ok:
Function SayLine() If gsApplicationName=="Outlook" Then ; In Outlook, but in message body.Microsoft_Outlook_2007::SayFocusedObject() ; Call Outlook's SayFocusedObject function.
Return EndIf SayLine() ; Drops to the SayLine in default. EndFunctionYou're calling up the chain, but not the function that called the Word SayLine initially, so no problem with a loop.

In my understanding self will make explicit that the function being called is from the same jss file, but if this is true then the self key word isn't that usefull, sinse you can call the function without scope identifiers anyways and the compiler will assume you're referring to the version of the function defined in the current jss file. Another question is the following: can you use a scope identifier to a file you didn't referenced with a use statement (other than default)? And still another question ... can you provide me a sample about how one could call a function (up the chain)? Thanks, Marlon. 2008/1/15, Dennis Brown <DennisTBrown@xxxxxxxxxxx>:
Hi,Those are new "scope" identifiers, needed because Outlook 2007 uses Word asthe 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 focuschange. 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 tothe correct function, otherwise it would call the Outlook FocusChangedEvent,which would call the Outlook SayFocusedObject, and OutlookSayObjectTypeAndText, none of which are used in the message body in Outlook. So, in Outlook's FocusChangedEventEx, we caused it to look for the class ofthe message body, _WwG, and if the current class, then redirect it to callthe Word's FocusChangedEventEx function, so the Word functions could processthe 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 tobe 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.
