On the C64, a single line (line number LN, with 0 <= LN <= 24) can be erased with POKE 781,LN : SYS(59903) Copying one line to another is also available: to move a line from line number LF to line number LT (0 <= LT,LF <= 24) POKE 781,LT: SYS(59888) : POKE 172,PEEK(60656+LF) : POKE 780, PEEK(216+MF) : SYS(59848) Finally, to scroll the screen up one line, SYS(59626) As long as you're reading this, let me put in a plug for "RUN" magazine. I have a subscription to it and to "Compute's Gazzette." If I had to give one of them up it would NOT be "RUN" as I find it to contain better, more technologically advanced articles and more helpful stuff. CG usually has *more* stuff in it, but much of it's not the stuff I want; most ot the time it's too elementary, and often cutesy. keith ericson at teklabs P.S. - only use these if you have purchased a copy of September "RUN" magazine...:-) P.P.S - '<=' means 'less than or equal'
