-- of a decimal type with the specified Scale, starting at S (P + 1) and
-- updating P to point to the last character stored, the caller promises
-- that the buffer is large enough and no check is made. Constraint_Error
-- will not necessarily be raised if this requirement is violated, since
-- it is perfectly valid to compile this unit with checks off. The Fore,
-- Aft and Exp values can be set to any valid values for the case of use
-- by Text_IO.Decimal_IO.
