perl，hash问题
请高手指教下，本人新手。。。

Write   a   perl   script   which   splits   the   table   into   a   hash   with   "EPS ",   "net   profit "   and   "profit   before   tax   &   items "   as   keys   and   the   number   as   their   value.   Make   sure   its   flexible   enough   to   work   with   different   quarters,   other   years   and   preferably   other   items   than   EPS   etc   i.e.   be   flexible   in   capturing   them   and   using   what   you   get   as   the   key.

Make   sure   currencies   are   handled   in   an   easy-to-update   fashion   (the   script   should   work   for   other   countries).

Please   note   that   numbers   must   be   ready   for   addition   and   multiplication   meaning   thousand-delimiters   and   currencies   must   be   removed   (of   course   the   currency   must   be   stored   in   the   hash).
