Well I'm not familiar with SGL so I can't give advantages of one over the other, but from what I've read about the Booch components, they seem to be field tested for a good few years, and very performant as far as Queues, lists, collections and all these features goes. I dont want to, nor would it be intelligent to attempt to reinvent the wheel and create my own if something this stable (perhaps SGL is stable too, I just never heard of it, not that I've been coding with Ada for many years either, still a rookie but I'm always getting better :-). Booch seems to have everything you could ever want in lists and lists management functionalities, and that's what I'm looking for. Where could I get and find out more about SGL?
