# ZX/TS P and R: PLOT/UNPLOT Tip and Action Attention Getter Program

Monthly programming tip: using RUN line_number to test a specific routine in isolation without executing the full program. Followed by the ‘Laurie G.’ demonstration program — a PLOT pixel hopping up and down a flight of steps — illustrating how PLOT/UNPLOT interacts with PRINT AT to wipe characters and create simple motion effects.
