MapColors() Alpha Question

I've read the reference about MapColors() and am very confused.

How would I go about setting an icon's alpha values to zero, and then having it go up to 100% alpha?

Ex:
proc/fadein()
  while(icon.alpha_value<=100)
    icon.alpha_value++

I realize that's not how you do it, but I'm stumped!

Like so:

// make icon totally opaque
icon.MapColors(1,0,0,0, 0,1,0,0, 0,0,1,0, 0,0,0,0)

// make icon totally transparent
icon.MapColors(1,0,0,0, 0,1,0,0, 0,0,1,0, 0,0,0,1)

Right but...
That wouldn't slowly fade to opque, it just seems to toggle it.

Is there a way to fade from totally transparent to fully opque?

Yes, it's pretty easy actually! It's something called the sleep() proc.
