 QUIT
 ;
 ; This routine is called by the HL7 package V1.6 to process
 ; incoming HL7 messages.  Expected variables are those
 ; documented in the HL7 package documentation.  The line
 ; tag is called if it is entered into the PROCESSING ROUTINE
 ; field for the server protocol.
 ;
ORR ; Process incoming ORR messages
ACK ; Process incoming ACK messages
ORM ; Process incoming ORM messages
ORU ; Process incoming ORU messages
