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.
EndFunction
This 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.
EndFunction
You're calling up the chain, but not the function that called the Word
SayLine initially, so no problem with a loop.
Hth.
Thanks,
Dennis Brown

Hello Dennis,
Can you explain again what is self used for? 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.
