view procedure names of packages

is there a method to list all procedures/functions of certain packages.

i know about dba_source but want to find an easier way

thx

In SQL*Plus, type "desc package_name".

for package´s proc & functions

select distinct object_name
from all_arguments
where package_name='DBMS_STATS';

for package´s procs & fncion´s arguments

select object_name, argument_name
from all_arguments
where package_name='DBMS_STATS'
