9PROCESS(MSGARR) ;Process ADT-A31 message received from MPI when a new
10 ; patient is assigned an Integration Control Number
11 ;
12 ;Input : MSGARR - Array containing ADT-A31 message (full global ref)
13 ; - MSGARR must be in format compatible with interaction
14 ; with DHCP HL7 package
15 ; MSGARR(1) = First segment of message

22 ;Notes : The MPI uses an ADT-A31 message to return the ICN of new
23 ; patients. This value (seq # 2 of PID segment) is the only
