Normally you draw something in plotscreen and then a fastcopy routine displays the contents of plotscreen on the lcd. The fastcopyb rom call displays the data where HL is pointing to. Could be useful when you have a program that looks all PICs on your calc up and lets you scroll through them. You would use the fastcopyb rom call then to display that PICture, instead of copying it to plotscreen first and then use a normal fastcopy routine.
