This is a parser for fixed length record files. You must specify an unpack pattern listing the widths of the fields e.g. {pattern=>'A3 A7 A20'}. You can either supply the column names or let the module get them for you from the first line of the file. In either case, they should be a comma separated string.
Refer to <http://perldoc.perl.org/functions/pack.html> for the formatting of the pattern.
Please refer to the documentation for AnyData.pm and DBD::AnyData.pm for further details.
