Changes the output displaying the radix point to the specified
    character. The radix point is the symbol that separates units
    from decimal fractions. For example, in the number 98.6, the
    period is the radix point.

    You must enclose the radix-char argument within single quotation
    marks.

    If you do not specify an alternate character, the default is
    either the period (.)  or the value specified by the logical name
    SYS$RADIX_POINT.
