 ;          **** TO BE CALLED WITH AN EXTRINISIC CALL ****
 ;Example:  I $$SDIMO^SDAMA203(CLIEN,DFN) S APPTDT=SDIMO(1) K SDIMO(1)
 ;
 ;INPUT
 ;  SDCLIEN      Clinic IEN (required)
 ;  SDPATDFN     Patient DFN (required)
 ;  
 ;OUTPUT
 ;  The extrinsic call will return one of the following values:
 ;     1   Patient has at least one scheduled appointment or checked-in
 ;         visit in an authorized clinic
 ;     0   Patient has no scheduled appointments or checked-in visits
 ;         in an authorized clinic
 ;    -1   Clinic is not an authorized clinic, clinic is inactive,
 ;         or SDCLIEN is null
 ;    -2   SDPATDFN is null
 ;    -3   Scheduling database is unavailable
 ;  
 ;  If a 1 is returned, then SDIMO(1) = Encounter or appointment 
 ;  date/time in FileMan format
 ;   
 ;**********************************************************************
 ;   Special Logic:
 ; - In line tag SDVISIT, the ACRP Toolkit API EXOE^SDOE is called 
 ;   multiple times as needed.  This API returns the NEXT encounter, 
 ;   given a start and end date/time.  We want to check ALL encounters
 ;   for a match on clinic IEN
 ; - In line tag SDDATE, if the current time is between midnight and 6am,
 ;   the API will start to look for encounters and/or appointments on the 
 ;   previous day
 ;
 ;  Internal variables:
 ;  SDBACK   Contains the value to be returned from this call.  See 
 ;           above for OUTPUT values and corresponding definitions
 ;  SDCONT   Flag to indicate if processing should continue.  If
 ;           the patient has an encounter in an authorized clinic
 ;           today, then we can skip the last step and not look for
 ;           a scheduled appointment
 ;  SDFROM   The date to start searching for an encounter or appointment
 ;  SDAPPTDT Encounter or appointment date/time returned in SDIMO(1)
