A92: The constant mask




l am having this problem using put_sprite_mask...

mountain(top1,lines1)
int top1;
int lines1;
{
asm("
    move.w 8(%sp),%d1
    move.w 10(%sp),%d2
    move.w 0,%d0
    move.b 255,%d3
    lea mountains(%PC),%a0
    move.w %d2,mountains
    bra overmountain
mountains:
 dc.w 0
 dc.w 20
 dc.b 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
 dc.b 0,0,0,0,0,0,0,0,128,0,0,0,0,0,0,0,0,0,0,0
 dc.b 0,0,
        etc...

overmountain:
");
put_sprite_mask();
};

This draws the huge sprite, but it does not use the mask (11111111 - 255) for 
some reason.  It acts as though the constant mask is 00000000.  Why is 
put_sprite_mask not functioning correctly?
