Additional Changes

·	Pre-Compiled modules and libraries are now supported.

·	Unreferenced code is automatically removed from the compiled program to minimize the executable file size. This can be overridden using the #OPTIMIZE OFF metastatement.

·	There is a dramatic improvement of execution speed in many/most DWORD expressions.

·	Dramatic improvement in GRAPHIC execution speed.

·	Mask variable assignment expressions may contain any combination of LONG and DWORD values without error. Operators may include +, -, AND, OR, XOR.

·	WSTRING, WSTRINGZ and WFIELD wide Unicode strings data types are now supported.

·	Variant variables now recognize the %VT_DECIMAL data type and now may contain UDT data as a string of bytes (%VT_BSTR).

·	Many new predefined numeric equates and string equates have been built-in to the compiler. One new equate is %PB_COMPILETIME which contains the date and time of compilation. See the Built-in string equates and Built-in numeric equates topics for a complete list.

·	Run Time error code 98 added: XPRINT PREVIEW error

·	Compiler error code 444 added: PREFIX clause expected. A PREFIX clause is expected in this statement.

·	Compiler error code 461 changed: INSTANCE arrays must be declared. INSTANCE arrays must be declared before any CLASS code.

Compiler error code 465 changed: May be defined only once. A program element which should only appear once was duplicated in your program. For example, two #STACK metastatements could cause this error to be generated. A common source of this problem is multiple #INCLUDE files which define the same term.

Compiler error code 466 changed: This name is already in use. This name (identifier) is used for more than one purpose, causing a fatal conflict. For example, you might have used the name ABC as both a variable and a label. You must rename one or both uses of this particular name. PowerBASIC generates this error when it sees the second use of the name.

·	Compiler error code 468 changed: This equate may not be redefined. A numeric or string equate is defined a second time with a different value. Equate definitions may appear more than once, but the value must remain constant.

·	Compiler error code 500 update: Variable name must be unique. All Global, Threaded, and Instance variable names must be unique to guarantee access to a specific variable. If #UNIQUE VAR ON is specified, then all variable names must be unique.

·	Compiler error code 503 changed: Invalid MAIN Function(s). Main/ LibMainFunction(s) do not match the target file type.

·	Compiler error code 512 changed: Brackets not supported (use OPTIONAL). Brackets are no longer supported for optional parameters.

·	Compiler error code 518 removed.

·	Compiler error code 540 changed: Invalid operation with a register variable. This assembler opcode or operands are invalid using a register variable.

·	Compiler error code 560 added: FASTPROC expected. A FASTPROC statement must precede other related statements like EXIT FASTPROC and END FASTPROC.

·	Compiler error code 561 added: END FASTPROC expected. A FASTPROC statement must be matched with an associated END FASTPROC.

·	Compiler error code 599 changed: Requires CLASS but outside of Interfaces. This item must be enclosed within a CLASS, but outside of Interfaces.

·	Compiler error code 606 changed: PowerCollection / LinkListCollection required. FOR EACH loops require an object of a specific class.

·	Compiler error code 607 added: New syntax requires GETCOM/NEWCOM/ANYCOM. The LET statement syntax for COM OBJECT creation has been changed. Previous syntax is no longer recognized.

·	Compiler error code 609 added: Too many macro expansions. You have used more than 65,535 macros in this program.

·	Compiler error code 610 added: Invalid within a FastProc. You have used a feature which is not supported within a FastProc.

·	Compiler error code 611 added: FASTPROC params must be ByVal Long Integer. FASTPROC parameters must be ByVal Long Integer.

·	Compiler error code 612 added: FASTPROC return may only be Long Integer. FASTPROC return value must be Long Integer or nothing.

·	Compiler error code 613 added: Cannot compile - the program is now running. The program you are trying to compile is currently executing. You may have to use Task Manager to force the program to end.

·	Compiler error code 614 added: Mismatched CHR Mode (ANSI/Wide). The string operand does not match the required ANSI or Wide mode.

·	Compiler error code 615 added: PREFIX expected. A PREFIX statement must precede each END PREFIX statement.

·	Compiler error code 616 added: END PREFIX expected. A PREFIX statement must be matched with an associated END PREFIX.

·	Compiler error code 617 added: ASMDATA expected. An ASMDATA statement must precede each END ASMDATA statement.

·	Compiler error code 618 added: END ASMDATA expected. An ASMDATA statement must be matched with an associated END ASMDATA.

·	Compiler error code 619 added: ENUM expected. An ENUM statement must precede each END ENUM statement.

·	Compiler error code 620 added: END ENUM expected. An ENUM statement must be matched with an associated END ENUM.

·	Compiler error code 621 added: Interface cannot inherit from itself. An interface cannot inherit from itself.

·	Compiler error code 622 added: AS STRING required for variant conversion. Conversion from a UDT as a string requires AS STRING notation.

·	Compiler error code 623 added: THREADPARM Instance variable required. THREAD Class must declare a THREADPARM Instance variable.

·	Compiler error code 624 added: Invalid THREADPARM variable type. THREADPARM must be a LONG, DWORD, or UDT PTR INSTANCE variable.

·	Compiler error code 625 added: THREAD Method required. THREAD Class must include a THREAD Method.

·	Compiler error code 626 added: Duplicate THREAD Method. THREAD Class must have exactly one THREAD Method.

·	Compiler error code 627 added: INHERIT IPowerThread expected. THREAD METHOD is only allowed with a threaded interface.

·	Compiler error code 628 added: Not valid in a Static-Link-Library (SLL). This language element is invalid in a Static-Link-Library.

·	Compiler error code 629 added: ALIAS disallows Private/Thread/Callback.

·	Compiler error code 630 added: Link File Error. The SLL Link File is not valid for this compiler.

·	Compiler error code 631 added: Nested Link Files. You cannot link an SLL file into an SLL file.

·	Compiler error code 632 added: COMMON name is a duplicate. COMMON procedure name was previously defined.

·	Compiler error code 633 added: COMMON signature is mismatched. COMMON procedure signature (params, return type...) is mismatched.

·	Compiler error code 634 added: Undefined COMMON reference. COMMON item was referenced but not defined.

·	Compiler error code 635 added: USING clause is required. USING <ProcName> is required to describe the function signature.

·	Compiler error code 636 added: Invalid VersionInfo Resource.

·	Compiler error code 637 added: This SLL requires CONSOLE (PB/CC only) or DDT support which is not available.

·	Compiler error code 638 added: Please change AS STRING to AS WSTRING.

·	Compiler error code 639 added: TYPE variable expected.

·	Compiler error code 640 added: Invalid use of BYCOPY. The BYCOPY override may not be used with certain parameters (for example, entire arrays).
