when you change the code to print out the values of $name, $1, and $2:
foreach $name (keys %book) { #write the data
print "$name \n";
$name =~ /(.+)&(.+)/;
print "$1, $2 \n";
if ($2 =~ /^0$/) {
print BOOK "$1,::";
} else {
print BOOK"$1,$2::";
}
for ( 0 .. $#{ $book{$name} } ) {
print BOOK $def[$_+2] . ":" . $book{$name}[$_] . "::" unless
+$book{$name}[$_] =~ /^0$/;
}
print BOOK "\n";
}
you get the correct output, and it shows $1 and $2 are initialized, but you still get the uninitialized error. Here is the output when you pass it School&0 and one number:
school&0
school, 0
# Use of uninitialized value, <> chunk 7.
File 'untitled:Desktop Folder:Will's Stuff:Applications:MacPerl ƒ:phonebook'; Line 57
so that isnt the problem. Loop lables are a good idea, though, thanks
