The EDIT STRING clause specifies the output format of a column
    value. SQL uses the EDIT STRING clause as the default format when
    writing a column value to a file or output device.

    To specify the format of a column value, use a string of one
    or more edit characters. Specify the edit string characters
    in single quotation marks without embedded spaces. In general,
    each edit character corresponds to 1 character position in the
    displayed output. For example, 999999 specifies that the output
    is 6 digits in 6 character positions.

    To enter more of the same edit characters, shorten the edit
    string by placing a repeat count in parentheses following the
    edit character. For example, the edit string 9(6) is equal to
    999999.

    You can change the character that SQL and DATATRIEVE display for
    the currency symbol ($),  decimal point (.), and digit separator
    (,)  edit string characters.

    To make your output conform to other conventions for numeric and
    monetary notation, override the system defaults for these symbols
    by redefining the following logical names:

    o  SYS$CURRENCY: Specifies the character SQL substitutes for
       the dollar sign ($)  edit string character. The default is a
       dollar sign.

    o  SYS$RADIX_POINT: Specifies the character SQL substitutes for
       the decimal point (.)  edit string character. The default is a
       decimal point.

    o  SYS$DIGIT_SEP: Specifies the character SQL substitutes for the
       comma (,)  edit string character. The default is a comma.
