tie %hash, 'GDBM_File', $filename, &GDBM_WRCREAT, 0640);
$filename is the text file read or is the db file name will be written to?

Read the pod in GDBM_File:
=head1 SYNOPSIS
use GDBM_File; tie %hash, 'GDBM_File', $filename, &GDBM_WRCREAT, 0640);
# you might want to test for error on the tie here
# Use the %hash array.
# Your code goes here
untie %hash;
open your text file and read line by line splitting on /\s*=>\s*/ and store in the hash - then untie hash and exit. I think DB_File might be a better choice than GDBM_File, but TEHO.
