Ada Constants and Corresponding Ingres Types
Note that, if the type or constant is derived from the SYSTEM package, the program unit must specify that the SYSTEM package should be included—EQUEL does not do so itself. You cannot refer to a SYSTEM object by using the package name as a prefix, because EQUEL does not allow this type of qualification. The types f_float and d_float and the constants max_int and min_int are derived from the SYSTEM package.
