Accessing array in MASM

Question

Hi guys,

let's assume I've got the address of my array (passed as a pointer to the function) in esi register. How can I access a particular cell of the array? i.e:

my_array[a + b * c]

where c is constant.

Thank you for the fast reply!

Cheers

Answer 1

Look up instructions such as LEA.

Think of it this way:

LEA edx,[esi+ebx*4]

Answer 2

you could directly move it as follows also:

MOV EDX,ESI[4*BX]

am not sure but i think it should work
