 ;This Program drives a real-time display monitor for the HL7
 ;Package. All the data used by this display is stored in file
 ;# 870. Several callable entry points were broken
 ;out of this routine and placed into HLCSMON1
 ;
 ;This routine has no required input parameters other than require that
 ;U be defined, it does not instantiate any parameters either.
