-- <PURPOSE>
-- Simple operations to execute a command in the OS environment.
-- Implemented by calling the ISO-C standard function "@system@".
--
-- Both versions of @Execute@ should be considered potentially blocking
-- calls.
--
-- Also provided is an interface to the ISO C standard function "@exit@",
-- which should kill the process.

-- <HISTORY>
-- 21-MAR-2002 TW Initial version.
-- 25-OCT-2002 TW Added @Terminate_Process@.
