The latest version of this topic can be found at Microsoft Macro Assembler Reference. The Microsoft Macro Assembler (MASM) provides several advantages over inline. Get this from a library! Microsoft Macro Assembler 5.1. The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows. Beginning with MASM 8.0 there are two versions.

Dear Macro Assembler Customer, This incremental update provides fixes for the problems described below. In general, the problems fixed are the ones most frequently reported to us. The next full update of Macro Assembler will address other problems.

If you find any other problems with the Macro Assembler, please contact us at (206) 454-2030. We are very interested in tracking all problems found with MASM to ensure that they are fixed in future releases. Your feedback is invaluable! Sincerely, System Languages Group Microsoft Product Support Services Problems Fixed in MASM 5.10a o Modified alignment constraints for variables allocated with the LOCAL directive. Padding bytes are used to enforce the following constraints: Type Specifier Align Type BYTE BYTE WORD WORD DWORD DWORD FWORD WORD QWORD DWORD TBYTE WORD Offset for local variables whose size is greater than WORD is now correctly calculated. O With /Zi, Codeview information is now generated for all symbols defined with the LOCAL directive. O The text macros for parameters and locals with the PROC directive are generated with surrounding parentheses.

This aids in their correct evaluation in expressions. O USES clauses in PROC directives no longer generates internal assembler errors. O Open procedures no longer cause listing file errors. O SUBSTR can now be used with the same label as both source and destination. O EXTRN ABS when C language is specified prepends name with an underscore. O Parameter alignment in 32 bit mode has been adjusted.

6 bytes were previously allocated for the return address, but 8 bytes are pushed by the calling program. O 32 bit fixup records are now being output in 16 bit code segments. O Unintentionally redefining a code label in a PROC no longer causes the assembler to hang. O MASM will now run in a VIO window under Presentation Manager. Problems Fixed in MASM 5.10a, Cont. O.CONST now generates a 'CONST' class segment as documented.

Previously, it was generating class 'DATA'. O /Z switch is no longer ignored after an include file is processed. O Can now mix / and in the command line source file path specification, i.e.: masm -t masm/src/file.asm; o Fixed GP fault on command line longer than 127 characters. O Fixed bug which caused errors to be reported with the wrong line numbers.

O Fixed a phase-error problem with: MOV BX, forward-reference expression o Fixed improper behavior when type missing on LABEL directive. O Real number initialization now works when.RADIX 16. Previously, a false 'non-digit in number' error was generated. O Can now initialize a structure field to a segment address. Previously, initializing a DD to a segmentName generated an invalid object file.

O% operator no longer inconsistently causes 'symbol not defined' errors when used with text equates. O Text macro expansions no longer cause GP faults.
