Re: A86: Link Tutorial




come to that, the system routines for writing characters to the screen
are kinda slow, too.  wanna include code for that in your programs?

link code has to wait for the other end to respond, and not much data is
typically transmitted, esp. in games.  if you wrote the link routines as
part of an interrupt routine, so it would work transparently alongside
your program, then it would be well worth the extra space.  ah well, i
suppose it's really a matter of personal preference in the end.
