So (especially if you're a teacher), just provide them a package with  =

useful stuffs of the like. This is how I first switched from a Pascal  =

dialect to Ada 95 : I could understand somethings, found it was not so  =

much easy at first glance, but still could create a package with  =

functionalities inspired from what's provided with typical Pascal progra=
m  =

; then later just dropped this.

The pending question may be now : when should students or beginners be  =

able to understand the concept of using an =E2=80=9Cexternal=E2=80=9D co=
mponent ? Perhaps  =

they should not start typing anything prior to that, and should start  =

learning, at the very beginning, listening someone recounting them nice =
 =

and happy stories involving basic abstraction principles :)

No-no, this isn't an oops ...or I hope (TM) - Don't blame me... I'm just=
