I come across LB's page: Please login to see this link.
and I found: MagicDeque @ Please login to see this link.
This is a Array Extension that is the best I found so far!
I put up this *.mfa example while learning HOWTO use MagicDeque!
Application menu doesn't work in PFO.mfa, I dunno why? (PFO.mfa is incomplete but still working)
So I make "PFO MDI.mfa" a MDI project of it because I know that the Application menu is working there.
I only use Push in my example but you can use: Shift, Insert and Push
You get a very good instruction guide to MagicDeque.
The Array is the base of almost every program, that's why I put in extra time to learn the MagicDeque!
