GETFIPS(DFN,INCYR,AIGMT) ;get the appropriate FIPS code and address for GMT
 ;
 ;INPUT:
 ;   DFN - internal entry number for the #2 file
 ;   INCYR - (optional) income year for which the GMT Address will
 ;           be returned. If this value is null, then this function
 ;           will not check for an existing GMT address (i.e. new
 ;           MT, conversion, etc.) but will follow all other
 ;           applicable rules. INCYR is in internal FILEMAN format
 ;
 ;OUTPUT:
 ;   The AIGMT array will be returned with the FIPS code and
 ;   address data used to compute the FIPS code.  The array will
 ;   be structured as follows:
 ;     AIGMT("INCYR") - Income Year used to compute GMT Threshold
 ;     AIGMT("FIPS") - FIPS County Code to compute GMT Threshold
 ;     AIGMT("MSA") - MSA code associated with this zip code
 ;     AIGMT("ST1") - Street Address 1
 ;     AIGMT("ST2") - Street Address 2
 ;     AIGMT("CITY") - City
 ;     AIGMT("STATE") - State
 ;     AIGMT("ZIP") - Zip Code
 ;     AIGMT("COUNTY") - County
 ;     AIGMT("GMTIEN") - ien for the GMT Thresholds file
 ;     AIGMT("SOURCE") - this field will contain the source of the
 ;                       address.
 ;     AIGMT("SITE") - this field will hold the site number related
 ;                     to the source if AIGMT("SOURCE")="MT"
 ;
 ;   If AIGMT("SOURCE")="PATIENT" then the address used for obtaining
 ;     the County FIPS code information was based on the Patient's
 ;     address in the #2 file.
 ;
 ;   If AIGMT("SOURCE")="MT" then the address used to obtain the
 ;     county FIPS code information was based on the Primary Means
 ;     Test location.
