passing an argument to mq process script

How to pass an argument to mq process script (or run it background in unix)

Example:

If we would like define a process which invokes the "luke.sh" script

and would like also passes the argument "lightsaber" to luke.

=== process definition ===

DEFINE PROCESS(P1) +
       DESCR ('MQ test process script') +
       APPLTYPE(UNIX) +
       APPLICID('/tmp/luke.sh') +
       USERDATA(' ') +
       ENVRDATA('lightsaber')
=== process definition ===

You must put the argument in the 'ENVRDATA' but not 'USERDATA'.

*** tip:

You can also put "&" in the ENVRDATA for the UNIX script running in the background.

****On UNIX systems, ENVRDATA can be set to the ampersand character (&) to make the 

    started application run in the background.
