Hello Douglas,

In systems with automatic garbage collection like Oberon
and BlackBox, prof.Niklaus Wirth and Juerg Gutknecht have
came to a conclusion initialize all variables. Because,
how you look itself undefined pointers with random bit settings?
Where it pointes and how garbage collector will be process its?
And so there was accepted decision to set all new pointers to NIL.

The situation with numercial variables not so unambiguous, and
better assign its obviously (additionally so more transparent),
but I faith that initialization variable in 0 has more advantage
and value, than in random bit simply.
