w_ctrl [-f config_file] [-l] [-v] [-o] [-c control_file] [command params]
When interactive loop mode is entered, any of the commands can be entered along with the command QUIT which terminates loop mode.
NB: Great care should be exercised when entering creating or updating program commands which have command parameters. If any of the parameters are standard options (with a leading '-') then thay should not be entered this way, but should be entered using interactive loop mode, or by pre-entering the details into a text file and issueing a load command.
