hi all,
I am having problems printing this doubly list. the bug statment prints the
expacted so I think I have the list setup right, but I cant get this list to
print in reverse... any ideas ??
Thanx in Advance
#!/usr/bin/perl -w
$debug=1;

$list = {value=>$i,prev=>$
For one, I would use the -d flag to use debugging options and set $^D to
whatever you want.
