[Bioperl-l] Problem in using BioPerl module through Strawberry Perl Professional 5.10.1.3 alpha 2

[2BioInfo]

Hi all,

I have been trying to use Bioperl through Strawberry Perl Professional
5.10.1.3 alpha 2 which by default has Bioperl modules

When I use

use Bio::SeqIO; ## It doesn't complain but when I use



  use Bio::Perl;

  # this script will only work with an internet connection
  # on the computer it is run on
  $seq_object = get_sequence('swissprot',"ROA1_HUMAN");

  write_sequence(">roa1.fasta",'fasta',$seq_object);


Then it shows following erros

Global symbol "$seq_object" requires explicit package name at C:
\...........\Perl\2.pl line 8.
Global symbol "$seq_object" requires explicit package name at C:
\...........\Perl\2.pl line 9.
Execution of C:\............\Perl\2.pl aborted due to compilation
errors.

Can you point me what I am doing wrong?
