You can implement mget by getting a list of files with 'ls', searching the files you want by passing the returned list through perl's 'grep' and performing a 'get' on the resulting list. Something like the following (untested):

    $ftp->get($_) for grep /\.txt$/, $ftp->ls;

$m.=substr('AHJPacehklnorstu',hex($_),1) }
