User Parameters in Shell Scripts
Job parameters and order parameters are accessible by use of environment variables. There is a naming convention: the name of the environment variable according to a parameter is SCHEDULER_PARAM_NAMEOFPARAM. For example the job parameter param1 is available by the environment variable SCHEDULER_PARAM_PARAM1.

Setting parameters and making them accessible to the next node in a job chain
At every change of status in a job chain JobScheduler parses a temporary file for name/value pairs. These name/value pairs will be set as order params. The name of the temporary file is availabe with the environment variable SCHEDULER_RETURN_VALUES.
