BWn – Extract the nth Word From a String

The BWn process returns the nth word from a string. For example, the fifth word in a string can be extracted by specifying number 5 in the process name.

The number specified in the process name must be a positive integer.

Words are delimited by spaces.

Note: If the number of words in a string is less than the number specified in the process name, a null string is returned and warning message CTB249W is written to the Rule Activity report.
