 ;This routine is used for the Version 1.5 Interface Only
HLFLDS(APP,SEG) ;Returns HL7 fields used by a DHCP application for a
 ;specified segment
 ;
 ;This is an extrinsic function call that returns a string containing
 ;a list of HL7 fields separated by uparrows (e.g., 1^2^3)
 ;
 ;Required variables:
 ;APP - the internal entry number of the DHCP application
 ;      from file 771
 ;SEG - the name of the HL7 segment for which fields are
 ;      to be returned
 ;
 ;Check for required input parameters
