This question is basically a C-programming question...
I have the following code in a program, which is set for 16-bit color:


BITMAP *OffScreen, *Texture;
... initialize these bitmaps ...

 short *SPtr;	                 //Short pointer to an offscreen bitmap
 SPtr = &((short*)OffScreen->line[Y])[X];  //Assign the pointer a value
					   //in the OffScreen BITMAP
				   

Now, in an inner loop, i have this code:

 *SPtr = ((short*)Texture->line[Y])[X];

Is there any way I can avoid casting to short* EACH time through the
loop?  For example, could I create a short* to Texture->line, and use
that through the loop?  Any help would be greatly appreciated!  Thanks
in advance...
