The Enterprise Health MGMT Platform (HMP) uses site
hashing to identify the individual sites that have treated a patient. The HMP
code is looping thru the Domain file (#4.2) using direct global access (read
only) in order to read the date in the Station field (#5.5) in order compare
the results to the Institution field (#.02) from the Treating Facility List
file (#391.91). When a match is made, the domain name (.01) field The Name
(#.01) from the Domain file (#4.2) for the matching entry is is used to create
the unique hash identified for the treating site.
All access to the Domain file is via direct global reads and with FileMan.
