Thanks Bruce,

I tried this but instead of <appname> -a returning the info required it
launches the application and thus is not recognised as a argument!!

I did remove:
sAbout = Args.Get("a", "about", "To test gb.args in GUI application")

Did it have to stay in?

And what if where now the line:
"To test gb.args in GUI application" 
it should actually say:
"Display about"
as I see it when doing a <appname> -h

And when doing the <appname> -a it should give:
"To test gb.args in GUI application" 
So that should be the value returned, but how to return the value?
And how to get the argument recognized?
