How to move register to an array?

[Intel_C_Intel]

I am using some inline assembly code in a C program, compiling with the Intel C++ compiler on Windows.

I need to move the contents of a register into an array.

char array[10];

char byte;

int index;

.

.

.

__asm

{

It should be something like this
(just a general idea):

char array[10];
char val;
int index;
....
__asm {
mov bl, val
lea edi, array
mov eax, index
mov BYTE PTR edi[eax],bl
}
