Receiving Answer Area Information from a MONITOR

When you invoke IXLLIST, list services return information related to your request in the answer area specified used the ANSLEN and ANSAREA parameters.

Under certain circumstances, answer area information is not valid. See Determining if the Answer Area is Valid for information on how to determine whether the answer area information is valid.
