This switch allows you to change the location of the HL7 Listener error report. By default, the report is named hl7errors.txt, and it is written to the root of the C drive on the server where the HL7 Listener is running.
Type the command line switch -HL7ERRORFILE="pathname"(where pathname contains a full UNC path, including the file name and extension) for the location where you want an HL7 Listener error report to be stored.
