normalize pointer

It depends on the type of the pointer you are using. If u are using a far pointer, then u should be normalizing but not the case for a huge pointer.
If you add values to a far pointer, only the offset is changed. If you add enough to cause the offset to exceed FFFF (its maximum possible value), the pointer just wraps around back to the beginning of the segment. For example, if you add 1 to 5031:FFFF, the result would be 5031:0000 (not 6031:0000). Likewise, if you subtract 1 from 5031:0000, you would get 5031:FFFF (not 5030:000F).
