Expressions in Definitions Changed for MASM 5.10 (38935)



The information in this article applies to:

  • Microsoft Macro Assembler (MASM) 5.1

This article was previously published under Q38935

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.
