        Added CreateXField support for PNP macro.  So now you can do:

            Name(BUF0, ResourceTemplate() {

                        IRQ(Edge, ActiveHigh, Shared, IRQ0) {

                                3,4,5,7,9,10,11,14,15

                        }

                        IO(Decode16, 0x100, 0x3ff, 3, 8, IO0)

                       }

            )

            CreateWordField(BUF0, IRQ0._INT, INTR)

            CreateWordField(BUF0, IO0._MIN, IOL)



0.9.21  Cleaned up error messages.

        Fixed a fault when generating .LST file.

        Added more semantic error checks.

        Allowed Index() as well as CreateXField to use PNP macro labels.

          For example:

            Index(BUF0, IRQ0._INT, Local0)



0.9.22  Added a new compiler directive "External".  The syntax is:

            External(<ObjName>, <ObjType>)

        This directive is to let the assembler know that the object is declared

          external to this table so that the assembler will not complain about

          the undeclared object.  During compiling, the assembler will create

          the external object at the specified place in the name space (if a

          full path of the object is specified), or the object will be created

          at the current scope of the External statement.  <ObjType> is

          optional.  If not specified, "UnknownObj" type is assumed.  Valid

          values of <ObjType> are:

            UnknownObj

            IntObj

            StrObj

            BuffObj

            PkgObj

            FieldUnitObj

            DeviceObj

            EventObj

            MethodObj

            MutexObj

            OpRegionObj

            PowerResObj

            ThermalZoneObj

            BuffFieldObj

            DDBHandleObj



0.9.23  Added _PIC in reserved object table.

        Added .ASM file generation.

        Improved .LST file generation.

        Renamed some of the command line options to be more like the Microsoft

          C compiler.



0.9.24  Fixed command usage help text.

        .ASM/.LST: Fixed Method invocation.

        .ASM/.LST: Fixed constant terms in Package and Name.

        .ASM/.LST: Fixed keyword arguments.



0.9.25  Optimized EISAID() code generation.



0.9.26  Added a check to make sure Fields and BankFields do not have an offset

          outside of the OperationRegion range.

	Added _DCK in the reserved name table.

	

0.9.27	Added _FDI in the reserved name table.



1.0.0   Renamed to be ver 1.0.0 (the first final release candidate).



1.0.1   Added _DDN, _BDN in the reserved name table.

	Added type checking on SuperName to disallow PNP macro labels.

	

1.0.2	Added '*' for objects in NSD files to indicate object has temporary

	  life (i.e. objects created in methods).

	Added more semantic check code for checking proper child term class.

	

1.0.3	Fixed a bug on checking child term class involving nested "Include".

	Fixed a bug to complain on ASL source file without DefinitionBlock.

        CreateXField are now Object Creators instead of Type1Opcode.

        If, Else and While scopes will now allow Object Creator terms.

	

1.0.4	Added _REG in the reserved name table.



1.0.5   Added check to make sure integer values cannot exceed DWORD maximum.

        Added error message when offset in FieldUnit exceeds 0x1ffffff or

          field length exceeds 0x10000000.



1.0.6   Added code to allow specifying region space in OperationRegion as a

          number so that region space can be extended beyond the standard

          regions.

        Added _BBN in the reserved name table.



1.0.7   Added code to print AML code offset to NameSpace object dump at which

          the NameSpace object was created.

	

1.0.8	Redefined Interrupt Vector Flags of the Extended Interrupt Descriptor

	  resource macro so that low-active-edge and high-active-level are

	  allowed.



1.0.9   Added _SxD in the reserved name table.



1.0.10  Added code to fail forward references of PNP resource objects.

        Added code to check for incorrect number of arguments during method

          invocation.

        Fixed a bug that may result in skipping some object type/existence

          validations.



1.0.11  Added _GLK, _FDE, _S0D and _S5D in the reserved name table.



1.0.12	Added _BCL, _BCM, _DCS, _DDC, _DGS, _DOD, _DOS, _DSS and _ROM in the

	  reserved name table.

	  

1.0.13	Added an optional third argument to External so that it can be used

	  to specify the number of argument to the MethodObj.  If the third

	  argument is missing, it is assumed 0.  Currently, if the object

	  is not MethodObj, this optional argument is ignored.

	  e.g. External(ABCD, MethodObj, 2)



1.0.14 Added _PCT, _PSS, _PTC, _OSI, _CST
