Dialect
    Nodialect

    The Dialect qualifier is used to control whether truncation
    of string data during the loading of data is reported or not.
    This loss of data might be significant. RMU Load defaults to SQL
    dialect SQL99 which implicitly checks for and reports truncations
    during INSERT operations.

    o  /NODIALECT, /DIALECT=SQL89 or /DIALECT=NONE will not report
       any truncation errors, which is the "old" behavior of Rdb
       (prior to July 2008).

    o  /DIALECT=SQL99 (the default) will enable reporting of
       truncation errors. Note that truncation occurs if non-space
       characters are discarded during the insert.
