The information in this article applies to:
  • Microsoft Macro Assembler for MS-DOS, versions 5.0 and 5.1
  • Microsoft Macro Assembler for OS/2, version 5.1

SUMMARY

The code fragment in section 7.1.3 on Page 147 of the "Microsoft Macro Assembler Programmer's Guide" causes a warning A4031: "Operand types must match." There is an error in the example.

Change the line below 

   mov ax, [bx].month
to the following: 

   mov ah, [bx].month

MORE INFORMATION

Because the structure field month is defined as a byte, the assignment to a word register generates the operand-mismatch warning message. The change to a byte register resolves the warning. The following is also acceptable: 

   mov ax, word ptr [bx].month

Additional reference words: 5.00 5.10
