Hi All.
subj.
publisher "Next Handbooks"  (Australia) , author Jaye Gallagher, no ISBN.

This short book seems to be a good introduction to perl for programmers

however some of the example code seems suspect (and it's also not on the CD)

eg:

 Sub SumList {
 my ($total, $current) = (0, 0);
 while($current = pop);
   {
   total += $current
   };
 return $total;
 }

print sumlist ( 1, 2, 3, 4, 5);

shouldn't that "while" be

 while( defined $current=pop)

That aside I'm starting to see how someone could consider writing   FIDO
applications in perl,  pack and unpack look real handy...

hmm, lists can contain not only 0 but also undef.
maybe this would be better

 Sub SumList {
   my $total = 0;
     $total += pop while(defined);
   return $total
 }

or maybe use foreach instead?

I'm starting to like this language.

please let me know if I've made any mistakes.
