AL = mov esi,OFFSET myWords + 2 mov ax,[esi] ; c. AX = mov edi,8 mov edx,[myDoubles + edi] ; d. EDX = true. An indirect operand such as [eax + edi] can be passed to the INVOKE directive. true. The assembler checks the pointer type used with the ADDR operator against the pointer type declared in the PROC directive. For example, it prevents a pointer to DWORD from being passed to a procedure expecting an pointer to BYTE.
word register cannot be first operand: special register cannot be first operand: coprocessor register cannot be first operand: cannot change size of expression computations: syntax error in control-flow directive: cannot use 16-bit register with a 32-bit address: constant value out of range: missing right parenthesis: type is wrong size for register: structure cannot be instanced
false. answer: a. The MOVZX instruction can use a variable as the destination operand. a.

Indirect operands are specified by prefixing the operand with an asterisk (*) (ASCII 0x2A). Only jump and call instructions can use indirect
register, known as the stack pointer register. - The ESP register holds a 32-bit offset into some location on the stack. - ESP always points to the last value to be added to, or pushed on, the top of stack. - A stack is also called a LIFO structure (Last-In, First-Out) because the last value put into the stack is always the first value taken out.
We cannot shift the whole number. Since one operand must be in register, ax is used to read the lower and.
If the RPL field ("requested privilege level"--bottom two bits) of the first operand is less than the RPL field of the second operand, the zero flag is set to 1 and the RPL field of the first operand is increased to match the second operand. word register ‹ word register * sign-extended immediate cannot be used to determine if the upper half of the result is non-zero. (the first operand) and two

The first operand is a 16-bit word register or memory variable that contains the value of a selector. The second operand is a word register. If the RPL field of the second operand is greater than the RPL field of the first operand, ZF is set to 1 and the RPL field of the first operand is increased to match the RPL field of the second operand.
Pop Word off Stack The destination operand can be a general-purpose register, memory location, or segment register. The POP instruction cannot pop a value into the CS register, instead, the RET instruction should be The first, called POP2, became a standard in the mid-80's and requires SMTP to send messages.
However, this memory operand may also be the destination (or a combined source and destination), while the other operand, the source, can be either register or immediate. Among other factors, this contributes to a code size that rivals eight-bit machines and enables efficient use of instruction cache memory.
The assembler checks the pointer type used with the ADDR operator against the pointer type declared in the PROC directive. For example, it prevents a pointer to DWORD from being passed to a … 4.3 Operating on Different Sized Operands Occasionally you may need to compute some value on a pair of operands that are not the same size. For example, you may need to add a word and a double word together or subtract a byte value from a word value.
Move word at (seg:offset) to AX. A1. MOV EAX,moffs32* Copies the second operand (source operand) to the first operand (destination operand). The source The MOV instruction cannot be used to load the CS register. Attempting to do
