SYMPTOMS
Using Microsoft Macro Assembler (MASM) version 5.1, You may be able to correct "Illegal size for operand" errors by careful use of parentheses.
STATUS
Microsoft has confirmed this to be a problem in MASM version 5.1. This problem was corrected in MASM version 5.1a.
MORE INFORMATION
The following code demonstrates warnings, errors, and their solution:
dosseg .model small,c .data .code myproc PROC buffer:FAR PTR BYTE mov bx, WORD PTR buffer[0] mov ds, WORD PTR buffer[2] ; MASM gives an operand-size error. This is a precedence problem that ; you can correct with parentheses: mov bx, WORD PTR (buffer[0]) mov ds, WORD PTR (buffer[2]) myproc ENDP end
