Failing a Script

Use the fail() method to halt the script and display an error message. If the script is used on a step transition, this method also prevents the step from proceeding to the next screen.

Example expression:

-exp 'if (!step.hasValue( ::Batch ID:: )) { fail(::Batch ID step UDF is required::) }'

Note that this example also uses the hasValue function (see Handling Non-Existent UDFs/Custom Fields).
