At the risk of sounding redundant, wouldn't perl -w catch
the use of $avg when undefined, thereby making
the debugging easier? All the debug tips are great, but the
best one is letting perl debug for you with
use strict; and -w.
On a stylistic note, you might want to scope your variables
like this:
my ($a, $b, $c, $d);
Instead of this:
my $a;
my $b;
my $c;
my $d;
This should help keep your code from getting diluted with
relatively less important text. (The computation is
more important than the declarations, so it should also take
up more space on screen to help focus your mind.)
