Thanks!  I went thru the pcre one. And after most of the doubts being chased
away from my mind, new ones are popping up, which i'll again mail about :-)
And I found Posix component to be more simpler to understand :)
One thing I observed was that you had used CREGEXP object in pcre, and
no such object declaration in posix. The declaration of this object 
(which starts with a GB_BASE ob) is solely based on the components 
internal needs, isn't it?

So, all the events (mouse clicks, etc) are received by Gambas itself 
and our appropriate methods (which we register with Gambas) are 
invoked by Gambas at runtime whenever it receives any event. 
Am I correct?

Thanks to you too, Rob !! :-)
