I think that you need to specify each parameter as a separate argument. In your example, [EMAIL PROTECTED] would be one argument and ls would be another. One other point: I am not sure about this but I seem to recall that Unix System Services shell commands expect the first parameter to be the program invoked (ssh in your example).
You may also wish to inquire or search at MVS-OE (see http://www.marist.edu/htbin/wlvindex?mvs-oe) which is more focused on Unix System Services.
