Field Notes

The following notes apply to the Fields for the DataInfo parcel.

  • The FieldCount, n, is the number of items within the Data Field in the corresponding Indicator Mode Record parcels. It also is the number of data type and length pairs in this DataInfo parcel.
  • The Pair fields contains a description of the data type and length of the corresponding data item of the record parcel. That is, the ith pair of data type and length values in the DataInfo parcel corresponds to the ith data item in the Data Field of the Indicator Mode Record parcel. See Data Type for the possible data types.
    • If the data type of the ith data item is not decimal, then the length (maximum length for VARBYTE and VARCHAR) of the ith data item in the Indicator Mode Record parcel is represented in the DataInfo parcel as a 16-bit unsigned binary.
    • If the data type of the ith data item is decimal, then the total number of digits in the ith data item in the Indicator Mode Record parcel is represented in the DataInfo parcel in the first byte of the parcel body length as an 8-bit unsigned binary, and the number of fractional digits is represented in the second byte of the parcel body length as an 8-bit unsigned binary.
