NAME: >=

        FUNCTION:  Tests values for greater than or equal to

        OPERAND TYPE:  Compatible simple, string, or packed
                       string types

        RESULT TYPE:  Boolean

        NOTES:

        When the operands =, <>, <, >, >=, or <= are of simple
        types, they must be compatible types; however, if one
        operand is of a real type, the other can be of an integer
        type.

        Strings are compared according to their extended ASCII
        charactor set.  Charactor type values are treated as
        string types.

        Packed strings can be compared if they have the same
        number of components.

        Pointers are equal only if they point to the same object.
        Only equal, <, >, are valid pointer comparison operators.

        Sets are compared according to its members.
        a = b is True only if a and b contain exactly the same
        members;  otherwise, a <> b.
        a <= b is True only if every member of a is also a member
        of b.
        a >= b is True only if every member of b is also a member
        of a.

        When using the IN operator, it will return true when the
        value of the ordinal type operand is a member of the set
        type operand.
