You can also use

select o.name as ProcedureName

, db_name(parent_object_id) as DatabaseName

--, sm.definition

, o.create_date as CreateDate

, o.modify_date as LastAlteredDate

from sys.sql_modules sm

inner join sys.objects o on sm.object_id = o.object_id

Benefit is the definition here is nvarchar(max) whereas in information_schema.routines it is nvarchar(4000)

Cheers
