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.
