in thread "Use of uninitialized value" with many variables

Although I agree with your suggestion of using a hash in this instance, I would actually code it slightly differently.
my %txt = map { $_ => '' }
          qw{AnniversaryDate BirthDate EmailAddr
             FaxNo MobileMo
             ...
            };

When initializing hash keys all to the same value I've found this idiom helps me make fewer mistakes. It also means less repetitive typing. (For those of us who type slowly, that's important.)

    my %txt;
my @field = qw(
    AnniversaryDate
    BirthDate
    EmailAddr
    FaxNo
    MobileNo
    ...
);

@txt{@field} = ('') x @field;

      Actually, '' x @field just concatenates @field empty strings and returns that string. This still causes the warning.
      You probably had a typo, intending to say @txt{@field} = ('') x @field;.

      I still stumble over the hash-slice syntax. I guess I just have to keep working with it.

      Thanks for the reminder.
