DESCRIPTION

This macro becomes a NULL return if its argument is ERROR. It is a convenient quick return that makes sense in the KJB library, but be careful about cleanup! Often code with NRN()'s will leak memory on failure which is acceptable if the failure is rare, but this should be documented. Further, if the debug level is greater than 0, then a message is added to the list of messages using add_errror(); That line is: 
    (NRN on line [line] of [file].
DISCLAIMER This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
