HL7 APPLICATION PARAMETER LOOKUP    ICR (3036)

This IA will allow MPI/PD to lookup an entry in the HL7
APPLICATION PARAMETER (#771) file using DBS FileMan calls.

The IA is needed because of the release of two seperate but related patches.
DG*5.3*261 exports the ADT/HL7 EVENT REASON (#391.72) file which has a field
named HL7 APPLICATION PARAMETER (#.02).  This field is a pointer to the HL7
APPLICATION PARAMETER (#771) file.  Our data in ADT/HL7 EVENT REASON file is
initially exported with the HL7 APPLICATION PARAMETER blank.  The HL7
APPLICATION PARAMETER required for this field is being exported in RG*1.0*4.

RG*1.0*4 adds the HL7 APPLICATION PARAMETER, and a post-install process adds
that data to the ADT/HL7 EVENT REASON file.  Our IA will permit our
post-install process to lookup the new application with silent FileMan calls
and subsequently add that data to the ADT/HL7 EVENT REASON file.
