As Herbie deduced from some syntax incoherence, I have not 
kept my promise of checking with MetroWerks.  My G3 has 
been freezing at random every 15 min or so even when idle.
Can only hope to sort things out myself at the weekend.

Feel free to post corrections before me.

What I wrote for C is based on Harbinger&Steele or Marks, 
and as for C++ it's mostly Schildt's C++ from the Ground Up.

   Cheers
