This is the correct way of declaring a variable and initializing
it at run-time (e.g. if the variable has what C calls "automatic"
storage class).  For example:

void foo(void)
{
   int count = 4 ;

}

Then "count" gets initialized each time foo is called.

On the other hand, if you wanted the variable to be initialized
only once ("static" storage), then in C you would write:

static int count = 4 ;

and in assembly you would write:

count  db   4
