o  When the DCL verify process is enabled using the DCL SET
       VERIFY command or the DCL F$VERIFY lexical function, RMU Load
       writes the .rrd file being processed to SYS$OUTPUT.

    o  There is no equivalent to the VARCHAR or VARYING STRING data
       types in the record definition language because there is
       no support for these types in the OpenVMS Record Management
       Services (RMS) environment.

    o  The VARCHAR or VARYING STRING data type is a two-part type
       with an UNSIGNED WORD (16 bit integer) length prefix with a
       fixed TEXT portion. The length defines the actual data in the
       string.

       There is no equivalent to the VARCHAR or VARYING STRING data
       types in the record definition language as this type is not
       supported by the OpenVMS Record Management Services (RMS)
       environment.

       If you unload a VARCHAR column then it will be converted to
       a fixed length (space padded) TEXT field. However, TEXT to
       VARCHAR load and unload is handled appropriately when using
       the delimited format. In this format RMU Unload only outputs
       the text as specified by the length prefix of the VARCHAR
       column. Likewise, RMU Load uses the length of the delimited
       string to set the length in the database.

    o  If a field is not to be used during the load into the table,
       it can be ignored during the load using the FILLER attribute.
       This allows RMU Load to use a data file which has more fields
       than there are columns in the database table.

    o  The <name> referenced in the END RECORD clause must be the
       same as the name defined by the DEFINE RECORD statement.

    o  The record definition files are not used when the Record_
       definition qualifier is omitted. In this case RMU Unload
       generates a structured internal file format which contains
       both the record definition and the data. This format allows
       the unloading of LIST OF BYTE VARYING columns and NULL values.
       This format is the same as that generated by SQL EXPORT for
       its interchange (.rbr) file. Use the RMU Dump Export command
       to format the contents of this file for display.
