Hmm so the self identifier would add a kind of recursivity, sinse there's no way of doing that if you call a function with the same name without it, sinse jaws will use the default version of that function if you do that? Marlon 2008/1/16, Dennis Brown <DennisTBrown@xxxxxxxxxxx>:
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 indefault, there is no way to do that because the script set in question wouldnot 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 intothe 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.

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)?
