NO!

C800 is NOT the address! It is the SEGMENT component of a two part
address. But when used as STATED: g C800 , it would NOT cause a branch to
C800:0 as intended! Instead, it would go to OFFSET C800 of the current
segment! xxxx:C800
If you want offset 0 of segment C800, then the command must be: g C800:0
NOT g C800 !!!!!!!!!!
g C800:5 would, indeed, be correct for an offset of 5 within segment C800
BUT "g C800" is NOT going to work.
