 ;;1.6;HEALTH LEVEL SEVEN;**10,13,21,36,19,47,62,109,108**;Oct 13, 1995
 ;
 ; Purge data of the HL7 message in file #772 and #773.
 ;
 ; Patch 47 - For Purging Option scheduled on a recurring basis,
 ; numbers of days kept for various Status of message are stored
 ; in file #869.3, fields 41, 42, and 43.  Default values for these
 ; fields are 7, 30, and 90, respectively.
 ;
 ; Patch 36 - a message will never be purged if the new field, "Don't
 ; Purge" (#772,15), is set to 1.
 ;
