[Bioperl-l] Pulling down data from NCBI

Thank you guys for very quick responses.  My bad I trusted my fingers.

Now that this is working the output that I am getting is not what I
want. I am sure I am missing the correct way of doing it. So If I
search the Nucleotide db @NCBI for this accession number "
AAPP01000000", I see some 34 k records. What I need to do is pull down
those sequences as fasta files.

I am referring to
http://www.bioperl.org/wiki/HOWTO:EUtilities_Cookbook  but dint quite
find a similar example.

Thanks!
