UPD(FILE,DGENDA,DATA,ERROR) ;File data into an existing record.
 ; Input:
 ;   FILE - File or sub-file number
 ;   DGENDA - New name for traditional DA array, with same meaning.
 ;            Pass by reference.
 ;   DATA - Data array to file (pass by reference)
 ;          Format: DATA(<field #>)=<value>
 ;
 ; Output:
 ;  Function Value -     0=error and 1=no error
 ;  ERROR - optional error message - if needed, pass by reference
 ;
 ; Example: To update a record in subfile 2.0361 in record with ien=353,
 ;          subrecord ien=68, with the field .01 value = 21:
 ;    S DATA(.01)=21,DGENDA=68,DGENDA(1)=353 I $$UPD^DGENDBS(2.0361,.DGENDA,.DATA,.ERROR) W !,"DONE"

ADD(FILE,DGENDA,DATA,ERROR,IEN) ;
 ;Description: Creates a new record and files the data.
 ; Input:
 ;   FILE - File or sub-file number
 ;   DGENDA - New name for traditional FileMan DA array with same
 ;            meaning. Pass by reference.  Only needed if adding to a
 ;            subfile.
 ;   DATA - Data array to file, pass by reference
 ;          Format: DATA(<field #>)=<value>
 ;   IEN - internal entry number to use (optional)
 ;
 ; Output:
 ;   Function Value - If no error then it returns the ien of the created record, else returns NULL.
 ;  DGENDA - returns the ien of the new record, NULL if none created.  If needed, pass by reference.
 ;  ERROR - optional error message - if needed, pass by reference
 ;
 ; Example: To add a record in subfile 2.0361 in the record with ien=353
 ;          with the field .01 value = 21:
 ;  S DATA(.01)=21,DGENDA(1)=353 I $$ADD^DGENDBS(2.0361,.DGENDA,.DATA) W !,"DONE"
 ;
 ; Example: If creating a record not in a subfile, would look like this:
 ;          S DATA(.01)=21 I $$ADD^DGENDBS(867,,.DATA) W !,"DONE"
