Expressions in Definitions Changed for MASM 5.10

ID: Q38935

The information in this article applies to:

Microsoft Macro Assembler for MS-DOS, version 5.1
Microsoft Macro Assembler for OS/2, version 5.1

SUMMARY

In all versions of Microsoft Macro Assembler earlier than version 5.1, you could not have an expression with a larger than 16-bits in a definition. This has been changed in version 5.1.

MORE INFORMATION

In all versions of MASM before version 5.1, you could use constants of greater than 16 bits; however, you could not use an arithmetic expression to obtain a number larger than 16 bits.

The following is an example:


   DD 86400     <-  correct.
   DD 60*60*24  <-  incorrect. This would be truncated at the
                               16-bit value.

This feature has been implemented in version 5.1 so that both of the above declarations will yield the same answer.
