passing command line arguements in asm thru C !

hello
i'm writing this C program to run a asm. i want to pass command line arguements to this asm.
but when i use mov cx,argv[1], it says operand size conflict. may be because mov requires 1 byte and argv[1] is sending 2 bytes. what is the possible solution ?? i need to use command line arguements only, what is the other way out to do this ?

i'm also including a sample program. pls suggest me how to go abt it.

waiting for a quick response.

thanks
shruti !!




#include <stdio.h>
#include <conio.h>
#include<string.h>

void main(int argc,char *argv[])
{

FILE *fptr;
printf("in func\n");


_asm
{
MOV CX,0FF20H
MOV DX,3F8H

}


getch();
}

are you sending the address of argv[1] or the actual value? if you are sending the address you need a 32 bit register, because all addresses are 32 bits long. if you're sending the value, i assume a char value, it should be perfectly fine... is that what you mean? another way to do this... command line arguments go to the stack.not sure if when a C program runs, and puts them in argv[] if it clears it, but you could push them on the stack somehow and pop them in the asm.
